While the guts of the Kyocera Willcom WX331K Honey Bee might not be of interest to anybody outside of Japan - since they use the PHS (Personal Handyphone System) network - the design is quirky enough to make me wish Kyocera would re-engineer it as a GSM handset. 

The WX331K has a 2-inch QVGA display, Opera 7.1 browser, IrDA and is available in five colours.  It weighs a mere 73g and measures 42 x 120 x 9.9mm.
