Tethered Jailbreak For Non-A5 Devices On iOS 5.1 Released By iPhone Dev-Team, Download Now [RedSn0w 0.9.10b6]


Apple released iOS 5.1 midst the new iPad launch yesterday, to which there was no jailbreak available. However, that has all changed now, as the iPhone Dev-Team have releasedRedSn0w 0.9.10b6 to jailbreak iOS 5.1. There’s one small problem though, this is a tethered jailbreak, which means that you will have to connect your iOS device to your computer every time you want to reboot.
The iOS 5.1 tethered jailbreak is only for non-A5 devices, which means that it will only work with theiPhone 3GSiPhone 4iPod Touch 3GiPod Touch 4G and iPad 1. The iPad 2, the new iPad and the iPhone 4S are not supported. Also, if you want to preserve your baseband for unlock, then you should create a custom iOS 5.1 ipsw firmware and then get on with the jailbreak. Read more below:
Update #1:  First, please read and re-read the above warnings!  With all of that in mind, we realize that some of you non-A5 jailbreakers are itching to get to 5.1, even though there seems to be no compelling new feature there. Because of geohot’s limera1n exploit, those with devices earlier than the iPad2 can test the 5.1 jailbreak waters if they really want to, using redsn0w 0.9.10b6.  Here’s what you need to know:
  • 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
