As promised, the iPhone Dev-Team have just rolled out their “backup plan”, which is the redsn0w version 0.9.7b1, for untethered jailbreak for iOS 4.2.1. The just released revamped Redsn0w, which is currently available in beta version, will provide you an ability to untethered jailbreak your iPhone 4, iPad, and fourth-generation iPod Touch running iOS 4.2.1.
As of now, the iPhone Dev-team is asking some help to some Mac users who is willing to test their new method. However, due to the fact that the new Redsn0w untethered jailbreak is in beta version and it was designed for testing some jailbreakers reportedly experiencing some technical problems after they “untethered” their iOS device, these include disabling Bluetooth, no AirPlay support, mo YouTube support, as well as most apps from the iTunes App Store won't work
Below are some of the notes from the iPhone Dev Team:
• This is a beta tester program. It’s not a general release! Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!
• For the same reason, please don’t participate if you rely on the ultrasn0w carrier unlock. Wait for the final version!
• Until we fix some sandbox issues with bluetooth, the bluetooth functionality is disabled.
• This very first beta1 is limited to iPhone4, iPad, and iPod touch 4G.
• Cydia must have your 4.2b3 SHSH blobs saved on file. (As we approach a general release, we’ll provide a way to let you use locally saved hashes too).
• You must already have the usbmuxd software installed and running on your Mac (this requirement will eventually go away too). The correct invocation of the relay is just as that page says: “./tcprelay.py -t 22:2222”. 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. Please test it beforehand to save yourself some time!
• Please leave all feedback in the comments below (we really need your feedback to help develop it into a stable release!)
