Customer Question

I just bought the iPhone 3GS from a previous owner on Amazon.com. I have had the phone for about 3 days now and haven't had problems with it until this afternoon. So I restored the phone back to its previous settings and now it won't activate. It says there is no SIM card in it and there is. I can use the SIM card in my old phone..but the iPhone is not doing anything.
