iOS 5 beta 3 is jailbreakable by RedSn0w 0.9.8 b1. DevTeam hacker MuscleNerd has confirmed that the RedSn0w 0.9.8 b1 jailbreak works . All you have to do is to point it to a downloaded iOS 5 beta 1 firmware ipsw.
Today’s 5.0b3 can be jailbroken with last month’s redsn0w http://is.gd/6eek4Y (point it at 5.0b1 IPSW..devs only please!)
RedSn0w 0.9.8 b1 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 1.
You can download RedSn0w 0.9.8 b1 for Windows and Mac OS .
MuscleNerd recently Tweeted that iOS 5 beta 1 jailbreak is already available. DevTeam released Redsn0w 0.9.8 b1.
For now the jailbreak is tethered (you have to run redsn0w each time you reboot) and available for Mac OS X only. It will not activate your device, so you need have registered UDID. iPhone 3GS users with 06.15 baseband: redsn0w will get you past the iTunes restore error. This redsn0w will probably work on future versions of iOS 5.
MuscleNerd tweeted today that the recent redsn0w utility is able to jailbreak the iOS 4.1 beta2 on iPhone 3G and iPod Touch 2G. This is useful for developers only, however good news for everyone.
Here’s some info from the DevTeam wiki page:
If you’ve updated to 4.1beta2 on iPhone3G or iPod2G(non-MC), you can use this redsn0w from June to jailbreak. Just point it at the 4.0 IPSW (the public one, not the developer GM one).
(Yes – point it at the 4.0 IPSW even though you’re at 4.1beta2).
Don’t do this if you need the ultrasn0w carrier unlock!!
Note 1: This won’t hacktivate your iPhone3G – but for those with legit access to the 4.1beta2 this shouldn’t matter. Please don’t pirate Apple software
Note 2: If you’re at 4.1beta2 you’ll probably experience network problems after jailbreaking. Until a new version of redsn0w is released, you may need to rely on afc2 access (such as FunBox-like file browser programs) to manipulate your filesystem.
Note 3: This is recommended only for power users who can deal with the problems that will pop up as the JB apps fall further behind the beta firmwares.
