Apple has posted a document warning users that jailbreaking their iOS devices may cause instability, security vulnerabilities, shortened battery life, and other issues. The document was posted on February 3rd, the same day the Evasi0n jailbreak was originally expected to drop. Take a look:
Unauthorized modification of iOS can cause instability, security vulnerabilities, shortened battery life, and other issues
This article is about adverse issues experienced by customers who have made unauthorized modifications to iOS (this hacking process is often called ”jailbreaking”).
As designed by Apple, iOS and iPhone, iPad, and iPod touch are designed to work together reliably. Unauthorized modifications to iOS (”jailbreaking”) can cause numerous issues to the hacked iPhone, iPad or iPod touch. Examples of issues caused by these unauthorized modifications to iOS have included the following:
Instability: Frequent and unexpected crashes of the device, crashes and freezes of built-in apps and third-party apps, and loss of data.
Security vulnerabilities: Security compromises have been introduced by these modifications that could allow hackers to steal personal information, damage the device, attack the wireless network, or introduce malware or viruses.
Shortened battery life: The hacked software has caused an accelerated battery drain that shortens the operation of an iPhone, iPad, or iPod touch on a single battery charge.
Unreliable voice and data: Dropped calls, slow or unreliable data connections, and delayed or inaccurate location data.
Disruption of services: Services such as Visual Voicemail, Weather, and Stocks have been disrupted or no longer work on the device. Additionally, third-party apps that use the Apple Push Notification Service have had difficulty receiving notifications or received notifications that were intended for a different hacked device. Other push-based services such as iCloud and Exchange have experienced problems synchronizing data with their respective servers.
Inability to apply future software updates: Some unauthorized modifications have caused damage to iOS that is not repairable. This can result in the hacked iPhone, iPad, or iPod touch becoming permanently inoperable when a future Apple-supplied iOS update is installed.
Apple strongly cautions against installing any software that hacks iOS. It is also important to note that unauthorized modification of iOS is a violation of iOS end-user license agreement and because of this, Apple may deny service for an iPhone, iPad, or iPod touch that has installed any unauthorized software.
redsn0w allows owners of A4+earlier devices to install rocky-racoon two different ways:
backup/restore method similar to Absinthe and cinject
its traditional limera1n-based ramdisk install. If you have a lot of media on your A4 device (music, movies, TV shows, etc), then the ramdisk method is preferrred because it avoids any possibility of later problems related to syncing to iCloud (including Photo Stream and Music Match). The ramdisk method is not available for A5 devices or later because limera1n can’t be used. If you’d like to use redsn0w’s ramdisk method, just be sure to put the A4 device in DFU or Recovery mode before starting redsn0w (otherwise it will immediately start to use the backup/restore method).
We’ve also added a new redsn0w feature specifically for those who got in on the SAM unlock: you can now include your SAM tickets as part of your initial ramdisk jailbreak of iPhone4 or earlier, or alternatively you can upload your SAM tickets to any device after its been jailbroken. redsn0w accepts either the individual SAM activation ticket plist file, or the entire zip file created by redsn0w’s “Backup” button. As usual, redsn0w continues to cover all of its previous jailbreaks and untethers (so redsn0w-0.9.12b1 covers everything from 5.1.1 all the way back to 4.1).
PwnageTool also avoids any possible sync issues, but again it applies only to A4+earlier devices. If you unlock your iPhone with ultrasn0w or a commercial method, you must use PwnageTool to avoid updating your baseband otherwise you’ll lose the unlock. PwnageTool will also jailbreak+untether the AppleTV2,1 5.0_2B206f (unless you customize the IPSW further, you’ll have just basic SSH access to the device).
FireCore announced today that they have successfully jailbroken the Apple TV 2 with the latest iOS 5.1 (5.0). The jailbreak is tethered which requires the Apple TV to be connected to a Mac/PC when powering it on (each time).
Today we’re happy to release new versions of Seas0nPass and aTV Flash (black) that are compatible with latest 5.0 (iOS 5.1) software running on the ATV2.
What’s new in the 5.0 AppleTV software? Should I update?
New interface: - Fast, visual access to all content choices
Movie purchases in iCloud: Support for buying movies on Apple TV and playing back purchased movies from iCloud
Genius Recommendations: Recommendations for content on the iTunes Store based on previous rentals and purchases
Screensaver photos: New National Geographic photos built-in for screensaver
On-device sign-up: On-device sign up for content partners on Apple TV using your Apple ID
Updating to the new 5.0 software is not required, and all aTV Flash (black) features will continue to be supported on AppleTV versions 4.2 and later.
What about the ATV3, will this work?
Unfortunately not. Work is still ongoing for the ATV3, and we hope to have more news soon. For the latest updates be sure to follow us on Twitter.
