iPhone Dev Team have updated their jailbreak tool, redsn0w. redsn0w version b5 incorporates a fix for iBooks, this time involving DRM. @planetbeing wrote a utility called “crazeles” that overcomes jailbreak detection by iBooks that would cause about 10% of images to show incorrectly. This fix is similar to the “hunnypot” fix that @comex wrote for the 4.x jailbreak. As usual, you can choose to install the fix either by re-running redsn0w over your existing jailbreak (de-select Cydia if you do that), or by installing the corona package from Cydia (it’s the same set of files no matter which way you choose).

  • The untether is for iOS 5.0.1 on iPhone3GS, iPhone4, iPhone4-CDMA, iPad1, iPod touch 3G, iPod touch 4G
  • If you have one of those devices and are not on 5.0.1 yet, update now! The SHSH window is still open for 5.0.1 If you unlock via ultrasn0w or gevey, make sure you only get to 5.0.1 via a custom IPSW! See the guides at places like if you don’t know how. Once you’re at 5.0.1, use the latest redsn0w 0.9.10 to both jailbreak and untether.
  • If you’re already at 5.0.1 with a tethered jailbreak, you have two choices: either run redsn0w 0.9.10 over your current jailbreak (deselect “Install Cydia” if you do that), or install the Cydia package prepared by the chronic devteam. The patches are the same regardless of which you choose.
  • Some of you are using a hybrid 5.0/5.0.1 configuration. If so, do not attempt to install this untether over that setup! You will most likely get into a reboot cycle. Do a sync and fresh restore to 5.0.1 then install the jailbreak + untether.

redsn0w 0.9.10b5 for OS X
redsn0w 0.9.10b5 for Windows (run in administrator mode!)
