I have a cingular question . pls advice
Yesterday Night I unlocked my new Iphone (Thanks to all you ppl ), and tested it with Tmobile (USA).
Now My question is will this iphone work with my old cingular sim , or AtnT will charge me data per bytes for its usage.
I am afraid tht they might charge me for data as the iphone continuosly keeps updating itself. As of now I dont have any data plan on my cingular account. and the per byte data would be very expensive .
What would you ppl advice .
