Ok, so my girlfriend's mom has an iPhone 3G running firmware 3.1 It's never been jailbroken before, so there are no SHSHs on file with Saurik's servers. She would like to sell it, but before doing so would like me to jailbreak and unlock it. Is there an unlock available, specific to the OS 3.1. I do not believe there is a way for me to upgrade to 3.1.2 and avoid 3.1.3 because of the lack of SHSHs. Can anyone offer up any suggestions?
