Could someone help me please. Because AT&T was bought out by Cingular, they made me change my phone when they gave me a new sim card. Now I can't use my Nokia phone 6820(b) since cingular does not carry this phone. That sucks 'cause my sim card won't work in my AT&T phone. They tried to unlock my phone, but the code the guy at Cingular tried didn't work. Could you please help with a code that will work. THANK YOU - THANK YOU IMEI = 352968/00/171208/4 code = 0513249//080431dTY model 6820(b) Thnks again
