IOS jailbreaking#History of tools

Expanding the feature set that Apple and its App Store have restricted is one of the motivations for jailbreaking.{{cite web |url= https://arstechnica.com/apple/news/2010/12/iphone-jailbreaker-set-to-bring-cydia-to-mac-os-x.ars |title= iPhone jailbreaker set to bring Cydia to Mac OS X |author= Chris Foresman |date= December 13, 2010 |work= Ars Technica |publisher= Condé Nast |access-date= August 2, 2011 |archive-url= https://web.archive.org/web/20110821055315/http://arstechnica.com/apple/news/2010/12/iphone-jailbreaker-set-to-bring-cydia-to-mac-os-x.ars |archive-date= August 21, 2011 |url-status= live }} Apple checks apps for compliance with its iOS Developer Program License Agreement{{Cite web |title=Agreements and Guidelines - Support - Apple Developer |url=https://developer.apple.com/support/terms/ |access-date=February 9, 2023 |website=developer.apple.com |archive-date=February 8, 2023 |archive-url=https://web.archive.org/web/20230208175748/https://developer.apple.com/support/terms/ |url-status=live }} before accepting them for distribution in the App Store.

An example of unlocking an iPhone through a Jailbreak utility would be Redsn0w. Through this software, iPhone users will be able to create a custom IPSW and unlock their device. Moreover, during the unlocking process, there are options to install the iPad baseband to the iPhone.

Cybercriminals may jailbreak an iPhone to install malware or target jailbroken iPhones on which malware can be installed more easily. The Italian cybersecurity company Hacking Team, which used to sell hacking software to law enforcement agencies, advised police to jailbreak iPhones to allow tracking software to be installed on them.{{cite web|last1=Fleishman|first1=Glen|title=Hacking Team hack reveals why you shouldn't jailbreak your iPhone|url=http://www.macworld.com/article/2944712/hacking-team-hack-reveals-why-you-shouldnt-jailbreak-your-iphone.html|website=MacWorld|access-date=August 2, 2015|date=July 6, 2015|archive-url=https://web.archive.org/web/20150803084827/http://www.macworld.com/article/2944712/hacking-team-hack-reveals-why-you-shouldnt-jailbreak-your-iphone.html|archive-date=August 3, 2015|url-status=live}}{{cite web|last1=Heath|first1=Alex|title=New Jailbreak App Stalks All Of Your iPhone's Activity And Makes It Available Online|url=http://www.cultofmac.com/131805/new-jailbreak-app-stalks-all-of-your-iphones-activity-and-makes-it-available-online/|website=Cult of Mac|access-date=August 2, 2015|date=November 25, 2011|archive-url=https://web.archive.org/web/20150923004602/http://www.cultofmac.com/131805/new-jailbreak-app-stalks-all-of-your-iphones-activity-and-makes-it-available-online/|archive-date=September 23, 2015|url-status=live}}

On iOS devices, the installation of consumer software is generally restricted to installation through the App Store. Jailbreaking, therefore, allows the installation of pirated applications.{{cite web|last1=Hattersley|first1=Lucy|title=Now pirated iOS apps can be installed without jailbreak|url=https://www.macworld.com/article/670132/now-pirated-ios-apps-can-be-installed-without-jailbreak.html|website=Macworld|date=January 2, 2013|access-date=July 14, 2022|archive-date=July 14, 2022|archive-url=https://web.archive.org/web/20220714230856/https://www.macworld.com/article/670132/now-pirated-ios-apps-can-be-installed-without-jailbreak.html|url-status=live}} It has been suggested that a major motivation for Apple to prevent jailbreaking is to protect the income of its App Store, including third-party developers and allow the buildup of a sustainable market for third-party software.{{cite web|last1=Kazmucha|first1=Allyson|title=Jailbreak, app piracy, and the true cost of theft|url=http://www.imore.com/jailbreak-app-piracy-cost-theft|website=iMore|access-date=August 2, 2015|date=May 26, 2012|archive-url=https://web.archive.org/web/20150821073824/http://www.imore.com/jailbreak-app-piracy-cost-theft|archive-date=August 21, 2015|url-status=live}} However, the installation of pirated applications is also possible without jailbreaking, taking advantage of enterprise certificates to facilitate the distribution of modified or pirated releases of popular applications.{{cite web|url=https://thenextweb.com/apple/2013/01/01/low-down-dirty-iphone-app-pirates/|title=iOS App Piracy Continues, Now Without Jailbreak|last=Panzarino|first=Matthew|date=January 1, 2013|work=The Next Web|access-date=May 4, 2018|archive-url=https://web.archive.org/web/20180504225921/https://thenextweb.com/apple/2013/01/01/low-down-dirty-iphone-app-pirates/|archive-date=May 4, 2018|url-status=live}}

File:ScreenshotofCydia.jpg, a popular package manager installed on jailbroken devices]]A package manager or package-management system is a collection of software tools that automates the process of installing, upgrading, configuring, and removing computer programs. For jailbreaks, this is essential for the installation of third-party content. There are a few package managers specifically for jailbroken iOS devices, of which the most popular are Cydia, Sileo, Zebra and Installer 5.

Depending on the type of the jailbreak (i.e. 'rootless' or 'rootful'), different security structures may be compromised to various degrees. As jailbreaking grants freedom over running software that isn't confined to a sandbox typical to that of an App Store application, as well as modifications to system files, it ultimately allows for the threat of malware.

Users of a jailbroken device are also often forced to stay on an older iOS version that is no longer supported by Apple, commonly due to the unavailability of jailbreak on the newer versions. While using older versions of iOS is considered safe in most circumstances, the device may be vulnerable to publicly known security flaws.

In March 2021, jailbreak developer GeoSn0w{{Cite web|date=March 22, 2021|title=[Free Release] iSecureOS - iOS Security Application For Jailbroken Devices (v1.0 Beta 1)|url=http://www.reddit.com/r/jailbreak/comments/mab585/free_release_isecureos_ios_security_application/|access-date=October 1, 2021|website=r/jailbreak|archive-date=October 1, 2021|archive-url=https://web.archive.org/web/20211001235042/https://www.reddit.com/r/jailbreak/comments/mab585/free_release_isecureos_ios_security_application/|url-status=live}} released a tweak called iSecureOS which can alert the users of security issues found on their devices. The application works akin to antivirus software, in that it scans the files on the user's device and checks them against a database of known malware or unsafe repos.

In June 2021, ESET Research confirmed that malware did exist on one of the piracy repositories in the jailbreak community. The malware actively targeted iSecureOS to try to bypass the detection,{{Cite tweet|user=ESETresearch|number=1402174908680097792|title=The newer version of iOS/Spy.Postlo.A attempts to modify the definitions of @isecureos (iOS Security application for jailbroken devices) to avoid detection.|access-date=October 1, 2021}} but updates to the security app were quickly released and have mitigated the malware.

Jailbreaking of iOS devices has sometimes been compared to "rooting" of Android devices. Although both concepts involve privilege escalation, they do differ in scope.

Where Android rooting and jailbreaking are similar is that both are used to grant the owner of the device superuser system-level privileges, which may be transferred to one or more apps. However, unlike iOS phones and tablets, nearly all Android devices already offer an option to allow the user to sideload 3rd-party apps onto the device without having to install from an official source such as the Google Play store.{{cite web|last1=Hildenbrand|first1=Jerry|date=February 2, 2012|title=Android A to Z: What is sideloading?|url=http://www.androidcentral.com/what-sideloading-android-z|url-status=live|archive-url=https://web.archive.org/web/20140708073558/http://www.androidcentral.com/what-sideloading-android-z|archive-date=July 8, 2014|access-date=July 9, 2014|website=Android Central}} Many Android devices also provide owners the capability to modify or even replace the full operating system after unlocking the bootloader, although doing this requires a factory reset.{{cite web|title=HTC Bootloader Unlock Instructions|url=http://www.htcdev.com/bootloader|url-status=dead|archive-url=https://web.archive.org/web/20141027141227/http://www.htcdev.com/bootloader/|archive-date=October 27, 2014|access-date=October 26, 2014|website=htcdev.com}}{{cite web|title=Official Bootloader Unlock instructions|url=http://unlockbootloader.sonymobile.com#Sony|url-status=dead|archive-url=https://web.archive.org/web/20140707020506/http://unlockbootloader.sonymobile.com/#Sony|archive-date=July 7, 2014|access-date=June 4, 2020|website=sonymobile.com}}{{cite web|title=#unlocking-the-bootloader Google instructions on bootloader unlocking|url=http://source.android.com/source/building-devices.html|url-status=dead|archive-url=https://web.archive.org/web/20110521220428/http://source.android.com/source/building-devices.html|archive-date=May 21, 2011|access-date=October 26, 2014|website=source.android.com}}

In contrast, iOS devices are engineered with restrictions including a "locked bootloader" which can not be unlocked by the owner to modify the operating system without violating Apple's end-user license agreement. And on iOS, until 2015, while corporations could install private applications onto corporate phones, sideloading unsanctioned, 3rd-party apps onto iOS devices from sources other than the App Store was prohibited for most individual users without a purchased developer membership.{{cite web|last=Mayo|first=Benjamin|date=June 10, 2015|title=Xcode 7 allows anyone to download, build and 'sideload' iOS apps for free|url=https://9to5mac.com/2015/06/10/xcode-7-allows-anyone-to-download-build-and-sideload-ios-apps-for-free/|url-status=live|archive-url=https://web.archive.org/web/20170120175052/https://9to5mac.com/2015/06/10/xcode-7-allows-anyone-to-download-build-and-sideload-ios-apps-for-free/|archive-date=January 20, 2017|access-date=November 12, 2016}} After 2015, the ability to install 3rd-party apps became free for all users; however, doing so requires a basic understanding of Xcode and compiling iOS apps.

Jailbreaking an iOS device to defeat all these security restrictions presents a significant technical challenge.{{cite web|title=Unauthorized modification of iOS can cause security vulnerabilities, instability, shortened battery life, and other issues|url=http://support.apple.com/kb/ht3743|url-status=live|archive-url=https://web.archive.org/web/20130510123825/http://support.apple.com/kb/HT3743|archive-date=May 10, 2013|access-date=July 9, 2014|website=Apple Support|quote=[U]nauthorized modification of iOS is a violation of the iOS end-user software license agreement and because of this, Apple may deny service for an iPhone, iPad, or iPod Touch that has installed any unauthorized software.}} Similar to Android, alternative iOS app stores utilizing enterprise certificates are available, offering modified or pirated releases of popular applications and video games, some of which were either previously released through Cydia or are unavailable on the App Store due to these apps not complying with Apple developer guidelines.

Many different types of jailbreaks have been developed over the years, differing in how and when the exploit is applied.

When a jailbroken device is booting, it loads Apple's own boot software initially. The device is then exploited and the kernel is patched every time it is turned on. An untethered jailbreak is a jailbreak that does not require any assistance when it reboots up. The kernel will be patched without the help of a computer or an application.

A tethered jailbreak is the opposite of an untethered jailbreak, in the sense that a computer is required to boot the device. Without a computer running the jailbreaking software, the iOS device will not be able to boot at all. While using a tethered jailbreak, the user will still be able to restart/kill the device's SpringBoard process without needing to reboot. Many early jailbreaks were offered initially as tethered jailbreaks.

This type of jailbreak allows a user to reboot their phone normally, but upon doing so, the jailbreak and any modified code will be effectively disabled, as it will have an unpatched kernel. Any functionality independent of the jailbreak will still run as normal, such as making a phone call, texting, or using App Store applications. To be able to have a patched kernel and run modified code again, the device must be booted using a computer.

This type of jailbreak is like a semi-tethered jailbreak in which when the device reboots, it no longer has a patched kernel, but the key difference is that the kernel can be patched without using a computer. The kernel is usually patched using an application installed on the device without patches. This type of jailbreak has become increasingly popular, with most recent jailbreaks classified as semi-untethered.

Apple has released various updates to iOS that patch exploits used by jailbreak utilities; this includes a patch released in iOS 6.1.3 to software exploits used by the original evasi0n iOS 6–6.1.2 jailbreak, in iOS 7.1 patching the Evasi0n 7 jailbreak for iOS 7–7.0.6-7.1 beta 3. Boot ROM exploits (exploits found in the hardware of the device) cannot be patched by Apple system updates but can be fixed in hardware revisions such as new chips or new hardware in its entirety, as occurred with the iPhone 3GS in 2009.{{cite web|title = Apple adds jailbreak resistance to recent iPhone 3GS models|url = https://arstechnica.com/apple/2009/10/apple-adds-jailbreak-resistance-to-recent-iphone-3gs-models/|access-date = June 20, 2015|date = October 14, 2009|archive-url = https://web.archive.org/web/20150621040227/http://arstechnica.com/apple/2009/10/apple-adds-jailbreak-resistance-to-recent-iphone-3gs-models/|archive-date = June 21, 2015|url-status = live}}

On July 15, 2011, Apple released a new iOS version that closed the exploit used in JailbreakMe 3.0. The German Federal Office for Information Security had reported that JailbreakMe uncovered the "critical weakness" that information could be stolen or malware unwillingly downloaded by iOS users clicking on maliciously crafted PDF files.{{cite news|url=http://www.news-record.com/content/2011/07/08/article/security_holes_discovered_in_iphones_ipads|title=Security holes discovered in iPhones, iPads|last=Robertson|first=Jordan|work=News & Record|agency=Associated Press|date=July 8, 2011|access-date=July 9, 2011|url-status=dead|archive-url=https://web.archive.org/web/20110711154914/http://www.news-record.com/content/2011/07/08/article/security_holes_discovered_in_iphones_ipads|archive-date=July 11, 2011}}

On August 13, 2015, Apple updated iOS to 8.4.1, patching the TaiG exploit. Pangu and Taig teams both said they were working on exploiting iOS 8.4.1, and Pangu demonstrated these chances at the WWDC 2015.{{cite web|url=http://www.mobileswire.com/ios-8-4-1-jailbreak-status-updated/|title=Taig and Pangu working on Jailbreak for IOS 8.4.1 |archive-url=https://web.archive.org/web/20150923060032/http://www.mobileswire.com/ios-8-4-1-jailbreak-status-updated/ |archive-date=September 23, 2015}}{{Clarification needed|date=September 2022|reason=This doesn’t make sense.

On September 16, 2015, iOS 9 was announced and made available; it was released with a new "Rootless" security system, dubbed a "heavy blow" to the jailbreaking community.{{cite web|url=http://ioshacker.com/news/ios-9s-rootless-security-system-dubbed-as-a-heavy-blow-to-jailbreak-community|title=iOS 9's Rootless security system dubbed as a 'heavy blow' to jailbreak community|access-date=October 10, 2015|date=May 22, 2015|archive-url=https://web.archive.org/web/20151122034602/http://ioshacker.com/news/ios-9s-rootless-security-system-dubbed-as-a-heavy-blow-to-jailbreak-community|archive-date=November 22, 2015|url-status=live}}

On October 21, 2015, seven days after the Pangu iOS 9.0–9.0.2 Jailbreak release, Apple pushed the iOS 9.1 update, which contained a patch that rendered it nonfunctional.{{cite web|title = Apple's iOS 9.1 Shuts Down The Pangu Hacking Team's Jailbreak|url = https://techcrunch.com/2015/10/21/apples-ios-9-1-shuts-down-the-pangu-hacking-teams-jailbreak/|website = TechCrunch|access-date = November 11, 2015|first = Sarah|last = Perez| date=October 21, 2015 |archive-url = https://web.archive.org/web/20151111113527/http://techcrunch.com/2015/10/21/apples-ios-9-1-shuts-down-the-pangu-hacking-teams-jailbreak/|archive-date = November 11, 2015|url-status = live}}

On January 23, 2017, Apple released iOS 10.2.1 to patch jailbreak exploits released by Google for the Yalu iOS 10 jailbreak created by Luca Todesco.{{Cite news|url=https://support.apple.com/en-gb/HT207482|title=About the security content of iOS 10.2.1|work=Apple Support|access-date=March 19, 2017|language=en-GB|archive-url=https://web.archive.org/web/20170216105636/https://support.apple.com/en-gb/HT207482|archive-date=February 16, 2017|url-status=live}}

On December 10, 2019, Apple used DMCA takedown requests to remove posts from Twitter. The tweet contained an encryption key that could potentially be used to reverse engineer the iPhone's Secure Enclave. Apple later retracted the claim, and the tweet was reinstated.{{cite web |last1=Clover |first1=Juli |title=Apple Used DMCA Takedown to Temporarily Remove Tweet With iPhone Encryption Key |url=https://www.macrumors.com/2019/12/11/apple-iphone-encryption-dmca-tweet-takedown/ |website=macrumors.com |date=December 11, 2019 |access-date=December 16, 2019 |language=en |archive-url=https://web.archive.org/web/20191213092141/https://www.macrumors.com/2019/12/11/apple-iphone-encryption-dmca-tweet-takedown/ |archive-date=December 13, 2019 |url-status=live }}

On June 1, 2020, Apple released the 13.5.1 update, patching the zero-day exploit used by the Unc0ver jailbreak.{{Cite web|last=Gartenberg|first=Chaim|date=June 1, 2020|title=Apple releases iOS 13.5.1, patching out the Unc0ver jailbreak|url=https://www.theverge.com/2020/6/1/21277281/apple-ios-13-5-1-patch-unc0ver-jailbreak-update-software-install|access-date=June 16, 2020|website=The Verge|language=en|archive-date=December 17, 2020|archive-url=https://web.archive.org/web/20201217073212/https://www.theverge.com/2020/6/1/21277281/apple-ios-13-5-1-patch-unc0ver-jailbreak-update-software-install|url-status=live}}

On September 20, 2021, Apple released iOS/iPadOS 15, which introduced signed system volume security to iOS/iPadOS, meaning that any changes to the root file system would revert to the latest snapshot on a reboot, and changes to the snapshot would make the device unbootable.{{Cite web |title=Signed system volume security in macOS |url=https://support.apple.com/guide/security/signed-system-volume-security-secd698747c9/web |access-date=April 15, 2022 |website=Apple Support |language=en |archive-date=May 14, 2022 |archive-url=https://web.archive.org/web/20220514042145/https://support.apple.com/guide/security/signed-system-volume-security-secd698747c9/web |url-status=live }} As a result, jailbreak development slowed considerably, and for the first time in jailbreaking history, the latest iPhone did not get a jailbreak before a new model was released.

On September 12, 2022, Apple released iOS 16, which introduced a new firmware component known as Cryptex1. New Cryptex1 versions are almost never compatible with old iOS versions, making downgrading impossible except within patch versions (i.e. 16.3 and 16.3.1).{{Citation needed|date=March 2023}}

The legal status of jailbreaking is affected by laws regarding circumvention of digital locks, such as laws protecting digital rights management (DRM) mechanisms. Many countries do not have such laws, and some countries have laws including exceptions for jailbreaking.

International treaties have influenced the development of laws affecting jailbreaking. The 1996 World Intellectual Property Organization (WIPO) Copyright Treaty requires nations party to the treaties to enact laws against DRM circumvention. The American implementation is the Digital Millennium Copyright Act (DMCA), which includes a process for establishing exemptions for non-copyright-infringing purposes such as jailbreaking. The 2001 European Copyright Directive implemented the treaty in Europe, requiring member states of the European Union to implement legal protections for technological protection measures. The Copyright Directive includes exceptions to allow breaking those measures for non-copyright-infringing purposes, such as jailbreaking to run alternative software,{{cite magazine |author=Duncan Geere |url=https://www.wired.co.uk/news/archive/2010-07/28/investigation-is-it-legal-to-jailbreak-a-uk-iphone |title=Investigation: Is it legal to jailbreak a UK iPhone? |magazine=Wired UK |date=July 28, 2010 |access-date=October 26, 2012 |archive-url=https://web.archive.org/web/20121031034914/http://www.wired.co.uk/news/archive/2010-07/28/investigation-is-it-legal-to-jailbreak-a-uk-iphone |archive-date=October 31, 2012 |url-status=live }} but member states vary on the implementation of the directive.

While Apple technically does not support jailbreaking as a violation of its EULA, jailbreaking communities have generally not been legally threatened by Apple. At least two prominent jailbreakers have been given positions at Apple, albeit in at least one case a temporary one.{{cite web|last1=Greenberg|first1=Andy|title=iPhone Uber-Hacker Comex Is Out At Apple|url=https://www.forbes.com/sites/andygreenberg/2012/10/18/iphone-uber-hacker-comex-is-out-at-apple/|website=Forbes|access-date=August 15, 2015|archive-url=https://web.archive.org/web/20150923004600/http://www.forbes.com/sites/andygreenberg/2012/10/18/iphone-uber-hacker-comex-is-out-at-apple/|archive-date=September 23, 2015|url-status=live}}{{cite web|last1=Heath|first1=Alex|title=After Doing "Insane Things With iOS," Jailbreak Hacker Winocm Joins Apple|url=http://www.cultofmac.com/267419/ios-jailbreak-hacker-winocm-joining-apple-later-year/|website=Cult of Mac|access-date=November 22, 2015|date=February 21, 2014|archive-url=https://web.archive.org/web/20151122234134/http://www.cultofmac.com/267419/ios-jailbreak-hacker-winocm-joining-apple-later-year/|archive-date=November 22, 2015|url-status=live}} Apple has also regularly credited jailbreak developers with detecting security holes in iOS release notes.{{cite web|title=8.4.1 release notes|url=https://support.apple.com/en-gb/HT205030|publisher=Apple|access-date=August 15, 2015|archive-url=https://web.archive.org/web/20150906165029/https://support.apple.com/en-gb/HT205030|archive-date=September 6, 2015|url-status=live}}

Apple's support article concerning jailbreaking claims that they "may deny service for an iPhone, iPad, or iPod Touch that has installed any unauthorized software," which includes jailbreaking.{{Cite news|url=https://support.apple.com/en-us/HT201954|title=Unauthorized modification of iOS can cause security vulnerabilities, instability, shortened battery life, and other issues|newspaper=Apple Support|access-date=February 14, 2017|language=en-US|archive-url=https://web.archive.org/web/20161223205502/https://support.apple.com/en-us/HT201954|archive-date=December 23, 2016|url-status=live}}

In 2010, Electronic Frontiers Australia said that it is unclear whether jailbreaking is legal in Australia, and that anti-circumvention laws may apply.{{cite web |url= http://www.pcauthority.com.au/News/223713,could-jailbreaking-your-iphone-land-you-in-jail.aspx |title= Could jailbreaking your iPhone land you in jail? |author= Rosalyn Page |date= August 5, 2010 |publisher= PC & Tech Authority |access-date= January 21, 2013 |archive-url= https://web.archive.org/web/20131021010517/http://www.pcauthority.com.au/News/223713,could-jailbreaking-your-iphone-land-you-in-jail.aspx |archive-date= October 21, 2013 |url-status= dead }} These laws had been strengthened by the Copyright Amendment Act 2006.

In November 2012, Canada amended its Copyright Act with new provisions prohibiting tampering with DRM protection, with exceptions including software interoperability.{{cite web |url= http://www.michaelgeist.ca/content/view/6692/125/ |title= Canadian Copyright Reform In Force: Expanded User Rights Now the Law |author= Michael Geist |date= November 7, 2012 |publisher= michaelgeist.ca |access-date= November 13, 2012 |archive-url= https://web.archive.org/web/20121109182709/http://www.michaelgeist.ca/content/view/6692/125 |archive-date= November 9, 2012 |url-status= dead }} Jailbreaking a device to run alternative software is a form of circumventing digital locks for the purpose of software interoperability.

The main law that affects the legality of iOS jailbreaking in the United States is the 1998 Digital Millennium Copyright Act (DMCA), which says "no person shall circumvent a technological measure that effectively controls access to a work protected under" the DMCA, since this may apply to jailbreaking.{{cite web |url=http://www.copyright.gov/fedreg/2012/77fr65260.pdf |title=Exemption to Prohibition on Circumvention of Copyright Protection Systems for Access Control Technologies |author=Copyright Office, Library of Congress |date=October 2012 |publisher=Federal Register |access-date=February 3, 2014 |archive-url=https://web.archive.org/web/20140104025052/http://www.copyright.gov/fedreg/2012/77fr65260.pdf |archive-date=January 4, 2014 |url-status=live }} Every three years, the law allows the public to propose exemptions for legitimate reasons for circumvention, which last three years if approved.

In 2007, Tim Wu, a professor at Columbia Law School, argued that jailbreaking "Apple's superphone is legal, ethical, and just plain fun."{{cite web |url= http://www.slate.com/id/2175304/ |title= The iPhone Freedom Fighters |author= Tim Wu |date= October 4, 2007 |work= Technology |publisher= Slate |access-date= October 26, 2011 |archive-url= https://web.archive.org/web/20110924084544/http://www.slate.com/id/2175304 |archive-date= September 24, 2011 |url-status= live }} Wu cited an explicit exemption issued by the Library of Congress in 2006 for personal carrier unlocking, which notes that locks "are used by wireless carriers to limit the ability of subscribers to switch to other carriers, a business decision that has nothing whatsoever to do with the interests protected by copyright" and thus do not implicate the DMCA.{{cite web |url=http://www.copyright.gov/fedreg/2006/71fr68472.pdf |title=Federal Register: Exemption to Prohibition on Circumvention of Copyright Protection Systems for |access-date=September 11, 2010 |archive-url=https://web.archive.org/web/20100710102554/http://www.copyright.gov/fedreg/2006/71fr68472.pdf |archive-date=July 10, 2010 |url-status=dead }} Wu did not claim that this exemption applies to those who help others unlock a device or "traffic" in software to do so.

In 2010, in response to a request by the Electronic Frontier Foundation, the U.S. Copyright Office explicitly recognized an exemption to the DMCA to permit jailbreaking in order to allow iPhone owners to use their phones with applications that are not available from Apple's store, and to unlock their iPhones for use with unapproved carriers.{{cite web |url=http://www.copyright.gov/1201/ |title=Copyright office provides exemption to DMCA |publisher=United States Copyright Office |date=February 12, 2009 |access-date=July 17, 2009 |archive-url=https://web.archive.org/web/20090806213422/http://www.copyright.gov/1201/ |archive-date=August 6, 2009 |url-status=dead }}{{cite web |url= http://news.cnet.com/8301-13578_3-20011661-38.html |title= Feds say mobile-phone jailbreaking is OK |author= Declan McCullagh |date= July 26, 2010 |work= CNET |publisher= CBS Interactive |access-date= October 26, 2011 |archive-url= https://web.archive.org/web/20111007193710/http://news.cnet.com/8301-13578_3-20011661-38.html |archive-date= October 7, 2011 |url-status= live }} Apple had previously filed comments opposing this exemption and indicated that it had considered jailbreaking to be a violation of copyright (and by implication prosecutable under the DMCA). Apple's request to define copyright law to include jailbreaking as a violation was denied as part of the 2009 DMCA rulemaking. In their ruling, the Library of Congress affirmed on July 26, 2010, that jailbreaking is exempt from DMCA rules with respect to circumventing digital locks. DMCA exemptions must be reviewed and renewed every three years or else they expire.

On October 28, 2012, the US Copyright Office released a new exemption ruling. The jailbreaking of smartphones continued to be legal "where circumvention is accomplished for the sole purpose of enabling interoperability of [lawfully obtained software] applications with computer programs on the telephone handset." However, the U.S. Copyright office refused to extend this exemption to tablets, such as iPads, arguing that the term "tablets" is broad and ill-defined, and an exemption to this class of devices could have unintended side effects.{{cite web |url=http://www.copyright.gov/fedreg/2012/2012-26308_PI.pdf |title=Exemption to Prohibition on Circumvention of Copyright Protection Systems for Access Control Technologies |publisher=U.S. Copyright Office |access-date=October 31, 2012 |archive-url=https://web.archive.org/web/20121119084311/http://www.copyright.gov/fedreg/2012/2012-26308_PI.pdf |archive-date=November 19, 2012 |url-status=dead }}{{cite web |author=Timothy B.
