I was interested in purchasing an unlocked HTC Hero but I wasn't sure how to configure it to the tmobile usa network. In the video posted by Rob Jackson here HTC Hero On T-Mobile USA: SIM Card Switcheroo | Android Phone Fans it shows him going into mobile network settings and configuring some things. If i were to get a hero would i have to do the same to get the phone working? If so how would i get that information. Thanks alot!
