Facebook mobile in Japan

[fuckedupjapan]

2 years since I got my vodaphone keitai. Time has come to change, and I'm fairly sure I want to change providers. 2 reasons for this:

- GPS, navi
- Facebook mobile, photo uploads

Has anyone tried uploading to their facebook accounts from either Au or DoComo? I can confirm that softbank doesn't work with it. How about videos? Anyone geeky enough to have tried twitter?

Thanks in advance~
