I'm having trouble with my phone. I lived in California and Had the phone working with Cingular as a provider. Now I'm living in Pennsylvania and I'm still using Cingular as my provider. When I got to PA I got a new contract with a new SIM card. Once I put the card in the phone it tells me "INSERT CORRECT SIM CARD". I don't understand why I would need to unlock the phone if it is the same provider. I was able to look in the setup of the phone and everything is unlocked except for the network.

Some one please help me.
