Hey there, I've tried the dct4 calc on the "nokiafreeunlock.com" or whatever it was, using the preconfiged settings...I've entered the code twice, and I get code error. Don't want to do this again unless I'm certain I'm getting the right code, and the phone is used, so I'm not sure if anyone's already attempted this. Its locked to Cingular Serial/IMEI: 353372004362584 Country: USA Carrier: Cingular Thanks!
