I don't hold much hope for a TMo Sprint union right now. Maybe once 4G is bigger and Tmo could use the WiMax network and convert it to LTE with a software upgrade, but right now, there are too many issues. And when has TMo shown Nokia love?? They don't have many Nokia models as it is, no Nokia smartphones, and don't look to offer the N900 from the early looks of it. That may change, but they have much invested in Cliq and MyTouch, and TP2 will as well. Just not room for the N900 from their perspective.
