Untethered jailbreak Redsn0w 0.9.7 for iOS version 4.2.1 is now available for download, the iPhone Dev-Team stepped in to say they had a back-up and would be releasing it this weekend.
Earlier, users were only able to jailbreak their iOS 4.2.1 devices with the tethered version which came with some constraints like connecting the device to a PC every time they switched it off which made untethered version a necessity.
At the moment the tool is only available for Mac at the moment. To be clear, redsn0w 0.9.7b2 only works to jailbreak iPhone 4, iPad, and iPod touch 4th generation, and only if the user has saved his / her iOS 4.2b3 SHSH blobs with Cydia.
However, the iPhone Dev Team warns that the tool is in its testing phase and if it is not implemented properly then things can go very wrong, causing their warranty to be void
Post related to Redsn0w reads:
We’re about to release the first beta using this new “backup method,” which redsn0w calls ‘Jailbreak Monte,’” the Team wrote on its blog.
The post continues with what the hackers call “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”. 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!)
Initially, there was a redsn0w 0.9.7 beta 1 release which had a few issues, but the Team quickly posted a second beta that only suffers from one bug – “Bluetooth disabled due to sandbox problem.”
Finally, the Team urges testers to test the redsn0w 0.9.7b2 jailbreak only a fresh restore.
The reason: “…otherwise it’s impossible to keep track of the variables involved,” according to the iPhone hackers.
