Download RedSn0w 0.9.9b6 For iOS 5 Jailbreak On Windows
The iPhone Dev-Team has just updated their iOS 5 jailbreak tool to support Windows. The latest version is RedSn0w 0.9.9b6 which brings quick iOS 5 jailbreaking to Windows and also fixes “Location Services” issue for iPhone 3GS devices running on the 06.15 baseband. Like the previous release, jailbreakers don’t need to supply the IPSW file manually since Redsn0w now includes the public URLs for the iOS 5 .IPSW files. Once again, the jailbreak is currently only tethered for all devices except iPhone 3GS with old bootrom. iPad 2 and iPhone 4S are not supported.
Via Dev-Team blog:
We’ve released version 0.9.9b6 of redsn0w, with both a functional fix and cosmetic fix for iOS5 jailbreakers. For iPhone3GS owners with the 06.15 baseband, this redsn0w eliminates the network crash you saw when using Location Services in iOS5 (in fact, you don’t even need to disable Location Services anymore during the initial setup). The cosmetic fix is to the visual countdown you see when going into DFU mode.
It’s okay to re-run this redsn0w over an existing device jailbroken at iOS5. Just choose “Jailbreak” again and de-select Cydia (in other words, all the checkboxes will be unchecked). If you are lucky enough to have an old-bootrom iPhone3GS, please pre-select the IPSW first (redsn0w can’t yet auto-detect the FW version of your old-bootrom 3GS if it’s already been jailbroken).
