Redsn0w 0.9.9b6 is up for download and this time, not just for the Mac OS X, but Redsn0w 0.9.9b6 is available for Windows also.
Redsn0w 0.9.9b6 eradicates the Location Services crashing issue on the iPhone 3GS (with iPad baseband) after the iOS 5 jailbreak.
Few days back, Redsn0w 0.9.9b5 was released, but it was available only for the Mac OS X. But this updated version of Redsn0w comes for Windows also.
If you aren’t using an iPhone 3GS on iPad baseband, then you can ignore this update. Else, as said above to solve the crashing issue, you can run Redsn0w 0.9.9b6 once.
Here is the official release notes from the iPhone Dev Team :
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).
