I got a subsidy unlock code from T-Mobile (my provider) to unlock my phone, which I did successfully. I then went and bought a SIM card from Cingular, but what I'm wondering is, is there any way to use that Cingular SIM card to pull service from one of their towers? I put the card into the phone, and when turned on, the phone brought up 3 Available AT&T towers, and I took turns trying to Register to all 3. They all acted like they connected successfully, but came back saying the network was "Unregistered...". Is there any way to fix this so that I can use their towers?
