I'd like to announce that I've compiled a DCT4 provider unlock codes generator (simlock) for Amiga. It allows you to remove provider locks for following phones: Nokia 1100, 2300, 3100, 3200, 3300, 3510, 3510i, 3650, 3660, 5100, 6100, 6220, 6230, 6310, 6310i, 6510, 6610, 6600, 6650, 6800, 6820, 7200, 7210, 7250, 7250i, 7600, 7700, 7650, 8310, 8910, 8910i, N-Gage
The readme file is minimalistic and if you use the program, it is assumed that you have read some unlocking guide for unlockers on PC.
