Do you lose any features if you unlock the phone for t-mobile? Does WIFI and other internet features work after the unlock? Also, you have to have a data plan to send emails, correct?
Hi, I only use WIFI but If you read these threads closely they tell you how to set up data recieving options if you have those in your plan. I would recomend you add "Dashboard" via cydia because you can manually turn edge or 3g on your phone and many other useful things like numeric battery in real time!
