This one strikes us as a bit fishy, especially considering the impending arrival of the Palm Treo 800w, but word on the street is that the aging Treo 700wx is set to receive a Windows Mobile 6 upgrade. Great news, but even more suspicious is that the upgrade specifically mentions WM 6.0, leaving out any trace of the current generation WM 6.1 version that is currently making the rounds. The rumor also conspicuously leaves out any mention of an update for Sprint users, referring only to a Verizon rollout. We suppose time will tell all, but until we actually see this thing hit the streets, we’re remaining skeptical. In the meantime, it looks like if you don’t to wait, you can unofficially get Windows Mobile 6.0 running on your Treo 700wx.
