Cool thanks. That's the same thing i came up with while searching Google. I emailed Horizon to see if they unlock it. Thanks for the help.

Just a quick question I noticed people saying that if I unlock my At&t 8900 the UMA won't work when I switch to T-Mobile? Is that the WiFi??

UMA is a service that requires WiFi to operate. It is true that the UMA will not work if you use an AT&T branded 8900 on the T-mobile network. The WiFi however, will work.
