Five hot new 3G cellphones from Japanese carrier KDDI today, including one, built by Casio, that has a digital camera with a resolution of two megapixels. The Sony Ericsson handset can play back TV shows recorded onto a Memory Stick (presumably with the PEGA-VR100K, Sony’s video recorder for handhelds), the Sanyo phone has a built-in FM tuner, and the Toshiba model can record video and then connect to a TV to watch it. All the phones feature KDDI’s new EZ Navi Walk GPS navigation service, which offers real-time scrolling and voice guided directions, as well as a feature which help you figure out how to get back home if you get lost.
