If you get an unlocked Sidekick, phone calls will work, text messages will work, internet will not work, mms will not work. There is no way to get those two to work on the AT&T/Cingular network either, unfortunately. It has to do with the network exchange or something like that, it is tied directly to T-Mobile's network, and the settings are not accessible to change.
