I have yet to see a clear cut answer on, and it would be nice to have a good understanding if I need to pay full price or not on Friday. For the people eligible for a Jump! upgrade, will we be able to use it for the pre-order on Friday? It seems like the pre-orders will be directly from T-Mobile but I'd just like to make sure that I can use my Jump! upgrade and it wont be an issue. They seem to be focused on At&t Next and that's about it.
