First, the necessary information: Model: Nokia 6230b Provider: Cingular Location: USA IMEI: 355032001103559 I've downloaded various software to calculate unlock code. However, when I enter the #pw+(xxxx)+(x)# I always get no response at all. I've also tried to enter the code with a different SIM...but seem to me that the sequence I've entered is wrong...i'm not sure if I should enter the whole sequence(as shown above) then press ENTER or just part of it, or the calculating software I download isn't correct... Please help me out. Thank you.
