@ jaredb3 - What you need to go is to settings -> wireless controls -> mobile networks into the APN settings then tap menu -> add APN then enter the following information:
name: att
username: wap.cingulargps.com
password: cingular1
then tap menu then save the APN and reboot your phone and you will be good to go...

www.unlock-tmobileg1.com I know its a website that claims to be able to but they actually do unlock them. Took less then 24 hours...
