You can jailbreak your phone and it will work perfectly with QTel, mime does. OS3.1.2 is fine and you will notice how much less battery it uses. I get 4-7 days out of mine here. (Turn off push though). It is not, apparently, illegal to jailbreak a phone just against the terms and service. Plus with jailbreak you can download xGPS and have a decent working gps system for far less than the rip-off price of a Garmin here.
