The following devices are supported:
iPod touch 3G
iPod touch 4G
iPad 1
iPhone3GS
iPhone4 (GSM)
iPhone4 (CDMA)

UNLOCKERS AND THOSE PRESERVING THEIR UNLOCKABLE BASEBANDS SHOULD STAY FAR AWAY FROM THIS! You will very likely lose your unlockable baseband if you try to install iOS 5.
THIS JAILBREAK IS INTENDED ONLY FOR DEVELOPERS OF JAILBROKEN APPS! There are just too many broken components (Apple’s official apps, 3rd-party App Store apps, Cydia apps, MobileSubstrate apps, etc) for this to be useful to anyone but those truly looking to fix bugs in their iOS 5 jailbroken apps. (Seriously!)
THIS REDSN0W WILL NOT HACTIVATE 5.0b1! You need to be an iOS developer with a registered UDID to get past all the new activation screens. PLEASE DON’T PIRATE APPLE SOFTWARE! Only registered devs with Macs can develop iOS applications, and only those people will have legitimate access to the beta IPSWs. See update #1 below.
THIS IS A TETHERED JAILBREAK ONLY! No new exploits are being exposed with this jailbreak (it uses geohot’s limera1n bootrom exploit), but that comes at a cost. You will need to use redsn0w to “Just boot tethered now” to be able to use many things, including Cydia and Safari. If you see a white icon for Cydia, or if Cydia or Safari crash when you open them, it’s because you didn’t boot tethered.
IF YOU HAVE THE 06.15 BASEBAND ON YOUR 3GS…this redsn0w will get you past the iTunes restore error you’ll get when using the stock IPSW (nobody other than those with the 06.15 baseband should be going anywhere near the stock IPSW!).

Update #1: Since Apple now provides Windows iTunes 10.5 for iOS5 and iCloud developers, it’s no longer the case that only Mac owners can legitimately activate their devices. We now provide a Windows version of redsn0w for those developers (only!).
Update #2: We’ve update redsn0w to account for the sandbox changes that affected App Store apps in 5.0b3 (and it now recognizes the IPSWs for all three betas so far). If you already jailbroke 5.0b3 using the previous redsn0w, you don’t need to re-jailbreak…just use this updated version to boot tethered. Start pointing redsn0w at the 5.0b3 IPSW starting with 5.0b3.
Here are the download links:
redsn0w 0.9.8b2 for Mac
redsn0w 0.9.8b2 for Windows
