Jailbreak iOS 5.1 with Redsn0w 0.9.10b6

Jailbreak iOS 5.1 with Redsn0w 0.9.10b6 for iPhone 4 / 3GS – iPad 1 / 2 – iPod Touch But note that is a Tethered Jailbreak Only.

As you can see, it really is a nuanced landscape so it’s sometimes
hard to drive the message home to new jailbreakers. But the basic rule
is the simplest (and it’s better to be safe than sorry!): If you
update to 5.1 you’ll very likely lose your jailbreak, so don’t do it!
Exceptions are noted above.




Now let’s see what Apple unveils today!
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 all versions of that older
  device.
  
• iBooks won’t work until a future update of redsn0w
