Hi, I have a strange problem with my 3GS 4.3.3. bb 6.15.00 I jailbroked and unlocked (switced to 6.15) without a problem, no lost of GPS or anything. I did that 2 moths ago in Norway were I live. For the moment I'm in Frace, and the minute I landed the phone didnt have network anymore. I searched for carriers and found 3 (Orange, Bougyes and SFR), the ONLY network that worked was Bougyes, I had full signal and all, BUT I couldnt call/recive or sms. Internet gps and all still works. I rebooted, reintalled both ultrasn0w and Carrier Reset fix (cydia.pushfix.info) numbres of times, and still didnt work. Everytime i reinstall ultrasn0w it says "Could Not Activate Cellular Data Network" I thought maybe the phone was confused using a norwegian sim card (Lebara) and choosing another carrier cause of the country, so yesterday I bought a sim card (Orange). And still nothing worked.. It says no network at the corner. Through General --> About it finds both Lebara and Orange in Carrier when using/changing the simcards.. What can be wrong?
