iOS Jailbreak

iOS jailbreaking

iOS jailbreaking is the process of removing the limitations on Apple devices running the iOS operating system through the use of software and hardware exploits – such devices include the iPhone, iPod touch, iPad, and second generation Apple TV. Jailbreaking permits root access to the iOS operating system, allowing the download of additional applications, extensions, and themes that are unavailable through the official Apple App Store. Jailbreaking is a form of privilege escalation, and the term has been used to describe privilege escalation on devices by other manufacturers as well. The name refers to breaking the device out of its "jail",^[5] which is a technical term used in Unix-style systems, for example in the term "FreeBSD jail". A jailbroken iPhone, iPod touch, or iPad running iOS can still use the App Store, iTunes, and other normal functions, such as making telephone calls.

Restoring a device with iTunes removes the jailbreak.

Unlike rooting an Android device, jailbreaking is necessary if the user intends to run software not authorized by Apple. The legality of jailbreaking depends on countries and conditions.

Reasons For Jailbreak

Use of third party apps

One of the reasons for jailbreaking is to expand the feature set limited by Apple and its App Store. Apple checks apps for compliance with its iOS Developer Program License Agreement before accepting them for distribution in the App Store.However, their reasons for banning apps are not limited to safety and security and may be construed as arbitrary and capricious. As the list of banned apps continues to grow, users rely on jailbreaking to circumvent Apple's censorship of content and features. Jailbreaking permits the downloading of programs not approved by Apple, such as customization apps used to change the User Interface.

Since software programs available through Cydia are not required to adhere to App Store guidelines, many of them are not typical self-contained apps but instead are extensions and customizations for iOS and other apps. Users install these programs for purposes including personalization and customization of the interface, adding desired features and fixing annoyances, and making development work on the device easier by providing access to the filesystem and command-line tools. Many Chinese iPhone owners jailbreak their phones to install third-party Chinese character input systems because they are easier to use than Apple's.

Use of handset on multiple carriers

Jailbreaking also opens the possibility for using software to unofficially unlock carrier-locked iPhones so they can be used with other carriers. Software-based unlocks have been available since 2008,with each tool applying to a specific iPhone model and baseband version (or multiple models and versions).

Early exploit fixes

On July 15, 2011, Apple released a new version of iOS that closed the exploit used in JailbreakMe 3.0. The German Federal Office for Information Security had reported that the "critical weakness" uncovered by JailbreakMe meant that iOS users could potentially have their information stolen or unwillingly downloaded malware by clicking on maliciously crafted PDF files. Before Apple released a fix for this security hole, jailbreak users had access to a fix published by the developer of JailbreakMe.

Device Customization

After "jailbreaking" their iPhone, owners can access almost unlimited customization, allowing for better "control" of the phone's settings, like the user interface, and color scheme. For iPhone users, this is the solution to the iPhone's restrictions, putting it in the same level of customization as Google's operating system, Android.

Security, privacy, and stability

The first iPhone worm, iKee, appeared in early November 2009, created by a 21-year-old Australian student in the town of Wollongong. He told Australian media that he created the worm to raise awareness of security issues: jailbreaking allows users to install an SSH service, which those users can leave in the default unsecure state.^[23] In the same month, F-Secure reported on a new malicious worm compromising bank transactions from jailbroken phones in the Netherlands, similarly affecting devices where the owner had installed SSH without changing the default password.

A Forbes staff analyzed UCSB study on 1407 free programs available from a third party source and Apple. Of the 1,407 free apps investigated in the cited study, 825 were downloaded from Apple’s App Store using the website App Tracker, and 526 from BigBoss (Cydia's default repository). 21% of official apps tested leaked device ID and 4% leaked location. Unofficial apps leaked 4% and 0.2% respectively. 0.2% of apps from Cydia leaked photos and browsing history, while the Apple store leaked none. He commented that unauthorized apps tend to respect privacy better than official ones. Also, there is a program called PrivaCy that allows user to control the upload of usage statistics to remote servers.

Installing software published outside the App Store has the potential to affect battery life and system stability if the software is poorly optimized or frequently uses resource-draining services (such as 3G or Wi-Fi).

Legal Status

Canada

In November 2012, Canada amended its Copyright Act with new provisions prohibiting tampering with digital locks, with exceptions including software interoperability.Jailbreaking a device to run alternative software is a form of circumventing digital locks for the purpose of software interoperability.

There had been several efforts from 2008-2011 to amend the Copyright Act (Bill C-60, Bill C-61, and Bill C-32) to prohibit tampering with digital locks, along with initial proposals for C-11 that were more restrictive,but those bills were set aside. In 2011, Michael Geist, a Canadian copyright scholar, cited iPhone jailbreaking as a non-copyright-related activity that overly-broad Copyright Act amendments could prohibit.

India

India's copyright law permits circumventing DRM for non-copyright-infringing purposes. Parliament introduced a bill including this DRM provision in 2010 and passed it in 2012 as Copyright (Amendment) Bill 2012. India is not a signatory to the WIPO Copyright Treaty that requires laws against DRM circumvention, but being listed on the US Special 301 Report "Priority Watch List" applied pressure to develop stricter copyright laws in line with the WIPO treaty.

Singapore

Jailbreaking might be legal in Singapore if done to provide interoperability and not circumvent copyright, but that has not been tested in court.

United States

Under the Digital Millennium Copyright Act, jailbreaking iPhones is legal in the United States, although Apple has announced that the practice "can violate the warranty".

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. 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. In 2012, the Copyright Office renewed the jailbreaking exemption for phones but declined to approve a new exemption for tablet computers such as iPads, due to the vague definition of "tablet" in the proposed exemption.The Copyright Office also renewed the 2010 exemption for unofficially unlocking phones to use them on unapproved carriers, but restricted this exemption to phones purchased before January 2013.

Tim Wu, a professor at Columbia Law School, argued in 2007 that jailbreaking is "legal, ethical, and just plain fun." Wu cited an explicit exemption issued by the Library of Congress in 2006 for personal 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.^[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 and 2012, the U.S. Copyright Office approved exemptions to the DMCA that allow iPhone users to jailbreak their devices legally. It is still possible Apple may employ technical countermeasures to prevent jailbreaking or prevent jailbroken phones from functioning, but it will not be able to sue users who jailbreak. It is also unclear whether it is legal to traffic in the tools used to make jailbreaking easy.

New Zealand

New Zealand's copyright law allows the use of technological protection measure (TPM) circumvention methods as long as the use is for legal, non-copyright-infringing purposes. This law was added to the Copyright Act 1994 as part of the Copyright (New Technologies) Amendment Act 2008.
