The hot word on the street is that Palm has all but confirmed the existence of two new phone models by ramping up a "launch developer" program for new applications. The devices, dubbed Zeppelin (a name we've heard quite a bit of) and Skywriter (which is new to us) could be slated for a Q3 release, as Palm is asking devs to turn in their applications by May 30th. Rumor has it that at least one of the units is a "Centro-like" Windows Mobile phone -- if that date is close to correct, it could very well be the "Wanda" that we saw back in January. The Zeppelin, on the other hand, is likely the WiFi equipped Treo 800w we've been hearing about for what seems like a million years. A mockup of a device (above) was included in the email, though we're pretty sure not even Palm could create a phone that ugly.
