Jailbreak For iOS 5.1 Now Available With Some Limitations

Jailbreak For iOS 5.1 Now Available With Some Limitations

March 8, 2012
The folks at The Dev-Team Blog have been busy since Apple officially released iOS 5.1 to the public. As such, a jailbreak for Apple’s newest iOS is now available. According to the team, those with devices earlier than the iPad 2 can test the 5.1 jailbreak using redsn0w 0.9.10b6. However, keep in mind:
  • This is a *tethered* 5.1 jailbreak for non-A5 devices. You’ll need to use redsn0w to “Just Boot” your device every time it power cycles, otherwise jailbreak apps won’t work (neither will Safari).
  • If you use ultrasn0w for your carrier unlock, be sure to use a custom IPSW to get to 5.1 first! Don’t ever restore to a stock Apple IPSW!  Use redsn0w’s “Custom IPSW” button to create a NO_BB_* version of the 5.1 IPSW and restore to that instead of the stock one.  (That option is available only to 3GS and iPhone4-GSM owners.)  ultrasn0w itself will be updated for 5.1 in the next few days (same baseband support, not 5.1’s baseband).
  • If you’re lucky enough to have an old-bootrom 3GS, this jailbreak is actually untethered (redsn0w will figure that part out automatically).
  • While we were at it, we added @pod2g’s steaks4uce exploit to support MC models of the iPod touch 2G (whose last firmware was 4.2.1).  So now redsn0w will auto-detect and jailbreak both MB and MC versions of that older device.
  • iBooks won’t work until a future update of redsn0w.
  For more information, please read the Team’s entire post on jailbreaking iOS 5.1. As a reminder, iOS 5.1 is relatively weak in terms of advancements. Among the new tools are Japanese language support for Siri and the ability to delete photos from Photo Stream. Additional features, including bug fixes are:
  • Camera shortcut now always visible on Lock Screen for iPhone 4S, iPhone 4, iPhone 3GS and iPod touch (4th generation)
  • Camera face detection now highlights all detected faces
  • Redesigned Camera app for iPad
  • Genius Mixes and Genius playlists for iTunes Match subscribers
  • Audio for TV programs and films on iPad optimized to sound louder and clearer
  • Podcast controls for playback speed and a 30-second rewind for iPad
  • Addresses bugs affecting battery life
  • Fixes an issue that occasionally caused audio to drop for outgoing calls
