The main feature of Redsn0w version 0.9.7 is ability to perform untethered jailbreak, whereas previous version of Redsn0w 0.9.6 can only perform tethered jailbreak. Please test it beforehand to save yourself some time! If the relay isn’t installed or running correctly by the time the redsn0w ramdisk has started, you’ll need to restore to stock FW again to try it again.

You must already have the usbmuxd software installed and running on your Mac (this requirement will eventually go away too).(As we approach a general release, we’ll provide a way to let you use locally saved hashes too). Cydia must have your 4.2b3 SHSH blobs saved on file.This very first beta1 is limited to iPhone4, iPad, and iPod touch 4G.Until we fix some sandbox issues with bluetooth, the bluetooth functionality is disabled. For the same reason, please don’t participate if you rely on the ultrasn0w carrier unlock.It’s not a general release!

Redsn0w 0.9.7 has been updated to support untethered jailbreak of iPhone, iPod touch and iPad running on iOS 4.2.1, which allows the iOS devices to be jailbroken (hacked) permanently (until the next firmware update), without the need to connect to computer for re-jailbreaking on every reboot, as required in tethered jailbreak. *As usual a big thanks to the iPhone Dev-Team for their hard work and contribution to the iPhone community.A new version of Redsn0w has been released by iPhone Dev Team.
