Hello, I wanted to sell my iPhone 2G 8Gb, found a customer and went to restore it for him. I obviously did something wrong, since the phone is now stuck in recovery mode and says 'NO SIM card installed, insert a valid SIM with no PIN lock to activate the phone.', also has a slide for emergency. Before this happened it was jailbroken, on iOS 3.1.3, with the whitedoor mode. I am from Croatia and it's a AT&T model bought in the states, I was running a T-Mobile card on it. Hope you can help me out with this one, thanks.
