WANT TO UNLOCK RAZORV3 TO WORK WITH SPRINT

The only reason that its not working is because Sprint locks their SIM cards so that you cannot use them on any other carriers. but it is possible. all you have to do is take the phone to AT&T and have them flash the phone to AT&T. another reason it won't work is because sprint is CDMA service, and AT&T is iDEN network and GSM. they aren't compatible. so you are unable to use the sprint SIM card in the AT&T phone. i am sorry.
