After iOS 4.2 was released, iPhone dev team – the most popular jailbreak team managed to jailbreak it and released the jailbreak too called redsn0w.
Only downside was, it worked untethered only with iPhone 3G or old bootrom iPod Touch 2G and iPhone 3GS. With iPhone 4, iPod Touch new gen, iPad the jailbreak was tethered only. This means you have to connected to your computer every time you reboot your iPhone to go into jailbroken state.
Untethered iOS 4.2 Redsn0w Jailbreak
Dev Team has released a new beta version of redsn0w which enables untethered jailbreak for iPhone 4, iPod Touch 4G, and iPad.
However, this is just for beta testing and comes with a lot of shortcomings. To start with, redsn0w beta is Mac only. Good news is in the past 3 days it has been out, it has come to 3 beta versions already.
Unless you know what you are doing, I highly recommend to wait for a stable redsn0w to be released, which should be just a few days of waiting.
Here is an excerpt of Dev Team updates
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”. 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!)
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.
Update #3: The third beta is now available (testers ONLY please!). This version extends the fix made in beta2 over to the non-GUI programs too (like the daemons that handle media content). That should cover things like Facetime, Winterboard themes, and embedded videos in iTunes. If you had trouble using the usbmuxd in previous betas, please wait until we incorporate that into redsn0w itself (i.e. don’t bother trying this beta3, just wait for the integration).
The download link is:
- redsn0w 0.9.7b3 (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.
If you try this beta version of jailbreak, let us know in the comments.
