Long story short: My friend came to me last night and asked me to unlock his iPhone3GS. I couldn't, because his was already on 4.0, I couldn't even downgrade it for him. So today, he traded with another friend and he has a iPhone3GS that's on 3.1.3 now. I couldn't jailbreak that to 4.0 either....so now we're looking at: His offer to trade iPhones with me(Mine is jailbroken at 3.1.2/3 i believe.) AND he's throwing in - $100 - his iPod Touch What should I do? It seems fine and all, but I really would miss all the free apps I can get thanks to it being jailbroken.
