my phone is getting cluttered so I wanna do a full restore. Right now I have a 32 3GS running version 3.0.1 (7A400), firmware err baseband 04.26.08. In cydia i have the "SHSHs on file for iPhone OS 3.1, 3.1.2, 3.1.3" I'm not sure which of that info is important, but I want my phone to be exactly the same os and baseband and everything after the restore. Also is there any reason to stay 3.0.1 and not 3.1? Is it only bad if I upgarde to 3.1.3? I also wanna keep the value for when i sell it in a few months. thanks!
