Are you using other sim cards compatible to att locked phones? Experiences so far? Is it not legal? I'm currently on AirVocie and their service is great! Fast internet. Really affordable compared to att. Bought the sim card for 2 bucks. Activated for free (the shop I bought it from offered to activate it for 10 bucks, they said I could call AirVoice and have it done for free). :)
