iPhone 4 storage problems!!

Hi All

I hope someone can help me, I have an iPhone 4 32g and usage is showing at 2g free and 26g used, problem is there is about 14gb unaccounted for, any ideas where it is being used or how to get it back????

Hi, obviously didn't make myself clear. I didn't feel the need to list where I can account for all the storage (iTunes 8gb, video 2gb, apps 2gb). the point is, I can't account for about 12-14 of the 26gb!! If I knew where it was I wouldn't have put the post up in the first place!!
