Here come the leaks, this time courtesy of Sprint. Phone news has a pretty clear idea of what's coming based on a leaked roadmap. The Windows Mobile highlights:

I've read elsewhere that the Treo 800w will have WiFi and GPS. I've heard rumors like the before regarding the Treo. These rumors - they are almost always lies. WiFi on a Treo - don't be ridiculous. More likely it will just be a Windows-version of the Treo 755p hardware [Edit: I meant 755p, not 700p. Thanks for the tip, D-Bo!], and I'm just fine with that. That's "just fine," and in "it's fine, but I still wonder why the heck Palm is so allergic to WiFi."
