In addition to the 03, Willcom has unveiled a pair of other handsets for release this summer on its Japanese PHS airwaves. The 03's a hard one to top -- pretty much any smartphone, a morphing keypad, and a WVGA display is going to make things tough on the competition -- but Sharp has a second entry in the trio with the D4. Like the 03, the D4 packs Windows Mobile and a full QWERTY board, but unlike the 03, the D4 flips up all Kaiser-style, which should be just perfect for showing off the WSVGA (yes, wide super VGA) display. On the simpler end of the spectrum, the Willcom 9 is a chunky, blocky flip with a QVGA display, 1.3 megapixel camera, and NetFront browser that'll be available in black or white. Kind of anticlimactic when you put it up against those other two, but not everyone wants a smartphone. No, not even in Japan.

Update: The D4 runs full-fledged Windows, not Windows Mobile -- makes more sense considering the monster specs. Thanks, everyone!
