bought a used iphone 3gs but edge/3g not working
I bought an iphone 3gs on ebay it had 3.1.3 ve 05.12.01 baseband unlocked it using spirit jailbreak and then ultrasnow 0.93 without any problems. now it works well including wifi but except the 3g/edge internet connection. when i open safari it says there is no internet connection. i checked cellular data settings many times but there seems no problem. The only thing is, previous user has some restrictions and it asks for a password. İs it possible to shut down 3g/edge from restrictions menu? Also, is there a way to restore the iphone to factory settings without losing the unlock or is it unlockable again after restoring? Will restoring help solving the problem?
Any comments or suggestions are appreciated.
