If anyone is interested - we've put up a unique keitai app to let people post a video message of support to the victims of the Wenchuan Earthquake. You need a 3G handset and just make a videocall to the number - 03-5338-0590.
Pretty much any Docomo will work, most new Softbanks. You'll know quickly if yours does or doesn't due to the fact that any that don't work are because the DTMF (keytone) is not compatible.
Messages are posted directly to YouTube on this channel (http://www.youtube.com/supportwenchuan)
It's a bit rough at the moment - but we're debugging and adding prettier and friendlier UI in the next day or 2.
