I just received my brand new iPhone 3GS from Apple, because my previous one died on me ... further details, check this thread. I took the new one out of the box, I let it charge for 12 hours like the guy at the store told me and now, when I put my SIM card in, which I've used before with my previous 3GS as well, iTunes says that the SIM is invalid. Very strange because I've used the same SIM card before. I tried DFU mode and recovering the iPhone, but the result stays the same. All I have now is a 'slide for emergency' bar at the bottom ... Does anyone if there's a solution to this without jailbreaking/unlocking? Thanks in advance! EDIT: Oh, by the way, I'm from Belgium. They only sell factory unlocked phones here, so I definitely shouldn't be getting that problem.
