Jailbreak iPhone 3GS on OS 3.1.3 with Spirit Untethered
As we have already reported, Spirit – the untethered userland jailbreak for iPhone 3.1.3 and iPad 3.2 has finally arrived. For the end user, Spirit looks and works very much like Geohot’s blackra1n, and is available for both Windows and Mac OS X.
Using Spirit, you can jailbreak (not unlock) all iPhone’s (iPhone (Edge), iPhone 3G and iPhone 3GS) and iPod touches (iPod touch 2G and 3G) running on the firmware version 3.1.3/3.1.2, and iPad and iPad 3G on firmware 3.2 – untethered.
Note for iPhone 3G and 3GS Unlockers: Do NOT upgrade to the stock iPhone 3.1.3 if you you want to keep your unlock as doing so will result in upgrade of your baseband, which will make it almost impossible for you to unlock. This is strictly for those who are either on official supported carrier like AT&T, or have already upgraded to 3.1.3 and are stuck with it.
IMPORTANT: Make sure that you have your SHSH files saved. You can jailbreak without saving SHSH files but you wont be safe once Apple patches the exploit used by Spirit. Follow the instructions posted here to save your SHSH blobs.
