Hi! I'm not too sure how this works or if I've pressed the right option, but I also have a Nokia 2600 Classic. I have already made 3 attempts using 2 different code calculators and got "code error"each time. My mobile details are: Model:Nokia 2600 Classic IMEI:3541 7002 4716 766 Network:Virgin I think I may have selected the wrong model (ie 2600 instead of 2600cn - I tried a code from both, but still no joy). Thank you very much in advance!
