Though you’ll have to wait a while for the privilege of owning an AT&T-branded Treo Pro, if you’re into that sort of thing your day of glory will come. During their quarterly earnings report, Palm confirmed that the Treo Pro will be officially released on an American carrier. Given T-Mobile’s non-existent relationship with Palm at this point, it seems clear that the intended customer is, in fact, AT&T. That’s good news, but given the lack of a confirmed date we’re left to speculate on the arrival time-frame. Palm mentioned that November would be a bit thin on the revenue side due to lengthy carrier certification processes, so it seems like December might be the most logical bet. Anyone going to hold off on a handset upgrade in favor of this Wi-Fi, GPS, and HSDPA equipped monster?
