Hi, I had a Nokia 6010, a GO Phone (Prepaid)from Cingular, which is now an At&T Company. I tried to get an unlock code by going on to two websites (unlock.it and lur.nu) that generated free unlocked code. I input my IMEI# and select the type of my phone which is a Dct3 Code. Then I tried to choose AT&T wireless, AT&T-3650, and Cingular Pacific Bell wireless as I did not know which one is supposed to be my carrier. When I purchased the service, it was cingular wireless, but now it is AT& T. I tried all the codes it generated about 5 times and kept getting "code errors" message. So can anyone help me out before my phone in permanently locked. Thank you so much in advance. My phone's IMEI# is 010559004009109 NOKIA 6010 (GO phone) Carrier: USA AT & T Thank you very much in advance.
