Hi, I want to unlock my nokia 1110i, which IMEI# is 353972012170521. It is currently locked to Bouygues Telecom (France, code 20820). I have already tried with Nokiafree code calculator, but it didnt work. Anyone could tell if: 1. This model can be unlocked like other dct4 phones; 2. How to unlock this model, if possible Thanks
