I talked to Tech Person from Sprint last night, who is working on fixing problems on the Sprint Touch, including the SprintTV issue and a few others. She said the update for the Touch has been pushed back. But it will include REV. A and GPS. She said the earliest it would be is June, but could be pushed back until August. But it is coming.
