Sanyo W31SA
We're convinced Japanese carriers drop handsets on us in fours or fives so they can slip in some average models along with the cool ones and avoid ridicule, but anyway: KDDI's latest Japan-only offering is the Sanyo W31SA, a squareish slider phone that records to SD card from either a mike or the inbuilt FM radio, and will play back audio ripped to the card. Unfortunately, they insist on you using a special card reader/writer and some proprietary software to get the audio onto the card, which is a dealbreaker as far as we're concerned. Oh yeah, and KDDI also released some other phones, but they were a bit boring.
