I have a Sony w810i and am using the Kagami theme package someone linked to in the general thread...
http://forums.animesuki.com/showpost...postcount=1284 is where celcius posted it.
It doesn't appear to come with a theme ringtone... but I like to use the light-hearted penny flute melody from Azumanga Daioh. I think its called "Maya To Ita Kisetsu". There's absolutely no one else in my city that uses it methinks and it turns heads...
