Ok so I've perused some of the threads on here about how to go about jailbreaking and unlocking the 2g iPhone running 3.0, but I'm still confused. Here's my situation: I bought a 3G S recently, so my 2g iPhone is pretty much obsolete now. Can I still jailbreak/unlock my 2g if it isn't currently activated? I'm going to sell it so how do I completely and safely wipe my data from the phone? Should my SIM card come out before the restore? And does my sim stay in during the jailbreak/unlock? So confused....any help would be great. Thanks a lot guys!
