How to Remove 560MB of Other?

[Zabumafu]

For some reason I have a ton of other and I do not know why. It happened right after ZIphone and now I have over 560MB of other on my iPhone and I do not know what it is. I have alot of music and videos but I don't keep my movies on there but yet upload them to my site so I can view them via safari.

Anyone know how I can remove it?
