Ok. Thank you. I have spent some time looking over the sight. I assume what you're saying is that I must unlock the phone to use the ATT sim card. What is the best source for me to learn to do this?
What if I want to switch back to the cingular sim card and migrate to Cingular? Will that be a problem?
I don't know exactly how to unlock it, but most likely you can find it out by searching the forums. If and when you switch over to Orange, you phone will work with either sim cards not just one.
