Word on the street (or via super-secret emails) is that Palm is about to begin beta testing on a fancy new device. Apparently, an email went out to select individuals calling for Sprint customers who will use Bluetooth devices and have access to WiFi. The email further requests that potential testers be "seasoned business professionals" who "commute and spend a ton of time working on email and on the phone." From the sounds of things, the company is gearing up to road test its heavily rumored, WiFi-equipped Treo 800w, a Windows Mobile device likely sporting 6.1. If you don't know what we're talking about, it's that mildly dated looking device from Gates' CES keynote that we've also seen in leaks recently. Nice going on the new spec and inclusion of WiFi (at long last) -- now how about some new form factors?
