Hey guys, i called cingular and got unlocking instructions and codes and the operator told me that it worked for both of my nokia 3100b's. It only worked for one of them, and when im using a certain sim card. the person did not tell me that it would permanently lock after 5 tries. Now i have 2 permanently locked phones. I searched the forum and saw that a "stock reset?" worked to completely reset the phones. Can anyone help me and let me kno if i can reset them? Thanks.
