Camera on iPhone stopped capturing

[jordygreen]

Since I have used ZiPhone to unlock and jailbreak my iPhone for some reason I can use the camera app to take a photo but then when I take a look at it in the photo album it is blank absolutely nothing in teh image. then when I go view it from the photos app it says there is no photo there which is strange :s
So I'm not too sure what to do about it, because I was at a gig last night taking photos all night and I have none now which sucks big time.

Any help would be great!
