Dell has confirmed that the only wireless carrier that its Android OS-powered Dell Streak tablet phone is going to fully support will be AT&T.
Users will be able to make voice calls on either T-Mobile or AT&T, and connect to both carrier's EDGE service, but this smartphone will support only AT&T's 3G network because T-Mobile's uses a different range of wireless frequencies.
Still, the Streak is going to offer
Wi-Fi, so T-Mobile subscribers could possibly get by using short-range wireless networking at their home and office and the 2.5G standard EDGE when on the move.
As the Streak is going to be a GSM device, Verizon and Sprint customers are going to be completely out in the cold.
