DevTeam hacker MuscleNerd has recently confirmed that the RedSn0w 0.9.8 b1 jailbreak works on iOS 5 Beta 2. All you have to do is to point it to a downloaded iOS 5 beta 1 firmware ipsw.
5.0b2 can be jailbroken w/redsn0w from 2 wks ago http://is.gd/6eek4Y (must point redsn0w at 5.0b1 IPSW)..devs ONLY please
This jailbreak works on all devices, exect iPad 2. This means you can get a tethered jailbreak on Windows and Mac OS for iPhone 3GS, , iPod Touch 3G, iPod Touch 4G and iPad.
You can download RedSn0w 0.9.8 b1 for Windows and Mac OS .
The iPhone Dev team has just released the second beta of their untethered RedSn0w jailbreak (the first beta has been released few hours ago and has more bugs).
New jailbreak is called “Jailbreak Monte”, as it uses new “backup method”. The iPhone Dev Team warns that their beta-version is not a general release and you should back up all your media before using it. There are also other limitations and bugs:
The beta is limited to iPod touch 4G, iPad and ;
The team asks not to participate in testing if you rely on the ultrasn0w carrier unlock;
The bluetooth functionality is disabled due to sandbox problem;
iPod player works only on iPod touch 4G;
To use this version of jailbreak Cydia should have your 4.2b3 SHSH blobs saved on file and following:
“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!”
Now, if you’re ready to apply this version of jailbreak, upi can download redsn0w 0.9.7 beta here.
After downloading and applying just select “Jailbreak Monte” to try out the untether.
The iPhone Dev team asks to test it after a fresh restore in order to keep track of the variables involved. Be careful!
By the way, iPodUplink has posted a video where you can see how to jailbreak your device with the latest version of redsn0w:
