Hey all, I had an unlocked 3GS baseband 6.15.00 and after switching to OSX Tiger, wanted to take advantage of IOS 5. After spending hours and hours making sense of conflicting webpages (most likely due to the date they were written), I ended up upgrading to 5.01 via iTunes and trying to jailbreak/unlock. I could jailbreak 5.01 using redsn0w, but ultrasn0w doesn't appear to be unlocking as the phone keeps saying "searching". I tried creating custom ispws but iTunes will not restore to anything but factory 5.01 (including a snowbreeze cooked 5.01 ispw). I haven't been successful downgrading back to 4.2.1 as iTunes will say it is "not eligible" along with every other ispw i try. I did use TinyUmbrella to save the blobs although I'm not sure where or when those will be useful. I'm assuming that I have to wait for ultrasn0w to become compatible with 5.01? My brain is going to explode trying to figure this out lol. Fortunately I have a backup 3G to use in the meantime. Thanks in advance.
