It looks like the Treo 610 is for real
Besides a bunch of people writing in to say that yes, those
details about the Treo 610 are accurate and that it is for real (where were all of you a few days ago?), the best evidence that the nail got hit on the head with this one is that palmOne is freaking out and starting to contact at least a few of the websites that have posted stories about it.
The only thing we haven't been able to sort out yet is what it's really going to be called, whether it'll be the Treo 610 or the Treo 660 or whatever, but right now we do know that it's codename is the "Treo Ace".
