Hello. I have recently purchased what I thought was an unlocked GSM Atrix 2 4G phone. It has the at&t logos on it. I purchased a SIM card from Straight Talk for the phone and it is a T-mobile SIM. The phone has been activated and everything is working but the browser. I am told by Straight Talk Technical Support that this phone must not actually be unlocked. I am either stuck having to try to hunt down a straight talk AT&T Compatible Sim, which is going to be like finding a needle in a haystack, or I can unlock the phone/have someone unlock it. I cannot find any instructions on how to unlock the phone in the forums here. Any help would be greatly appreciated with the utmost respect. 
revisement: ok from watching a youtube video on unlocking, it reminded me that if the phone was not unlocked that it would prompt you for a code upon booting up the phone if you inserted a "non-compatible" sim into it.. if this is true and my apn settings are correct, why would my browser not work?
