Redsn0w 0.9.7b1 For iOS 4.2.1 Untethered Jailbreak For iPhone 4, iPad And iPod Touch 4G Released

As expected, iPhone Dev team has just released a new version of Redsn0w (Redsn0w 0.9.7b1) that implements the “backup plan” for iOS 4.2.1 untethered jailbreak.
Redsn0w 0.9.7b1 can be used to (untethered) jailbreak iPhone 4, iPad and iPod touch 4G on iOS 4.2.1. Please note that Redsn0w 0.9.7b1 is meant only for beta testers and not for the general public as there are still some known issues that need to be addressed.
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: “./ -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!
Update #2: The second beta is now available (testers ONLY please!). This version should fix all the native app crashes (including Task switcher). That’s the only change in from beta1….Bluetooth is still disabled. If you had trouble using the usbmuxd in beta1, please wait until we incorporate that into redsn0w itself (i.e. don’t bother trying this beta2, just wait for the integration).

redsn0w 0.9.7b2 (OS X). Please test this after a fresh restore (otherwise it’s impossible to keep track of the variables involved). Select “Jailbreak Monte” to try out the untether.
Update bugs:
In addition to the known bugs, users are reporting the following problem:
- iPod app is not working for iPhone 4 and iPad users
- YouTube app is not working for some users
- Users reporting issues playing videos from the camera roll
- AirPlay is not compatible
- Users have reported that some iOS apps are crashing
