Much awaited Redsn0w 0.9.7 b1 is finally released now. The beta version will be helpful for untethered jailbreak on iOS 4.2.1. Redsn0w 0.9.7 b1 currently support untethered jailbreak on iPad, iPhone 4 and iPod Touch 4G. iPhone 3G and 3GS is not supported till now but they will soon be compatible with it.
As we know that Comex’s untethered jailbreak on iOS 4.2.1 is delayed and this is now a backup plan by iPhone Dev Team. Redsn0w 0.9.7 beta 1 calls “Jailbreak Monte” to accomplish the untethered jailbreak on iOS 4.2.1.
You have to have SHSH blobs saved of your iDevice in order for this jailbreak to operate.
iPhone Dev Team has posted an official note:
Update #1: We’re about to release the first beta using this new “backup method”, which redsn0w calls “Jailbreak Monte”. Here are some important points:
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”.
Please leave all feedback in the comments below (we really need your feedback to help develop it into a stable release!)
