PalmPower Contributing Editor Michael Compeau reported in from PalmSource yesterday with news that Palm has announced version 4.0 of its operating system. The new version supports 16-bit color, USB connections, and Bluetooth wireless connectivity. The fun didn’t stop there, however. Palm CEO Carl Yankowski also hinted at Palm OS version 5.0, which will allow for a higher resolution screen. Finally, Mike reported that Claudia Schiffer was in attendance to promote her Palm Vx Claudia Schiffer Edition, and he says she actually appears to be taller in person.
