Sony Ericsson P910
when I use my AT&T sim card, the phone keeps searching for a network but can not connect to any. It shows full reception but no network... how can that be? Could that mean that the phone is not unlocked? or may be I need to identify the network manually somehow using phone features??
If anyone knows the answer please let me know
I love that phone and really want to make it work with Cingular/former AT&T
Your help and advice is greatly appreciated
