is there any app for the iphone that will allow me to browse & edit documents & photos that are on the iphone?

i mean for example i have some photo folders apart from the camera album...but maybe i want to shift something from the camera album to one of them

apart from that...i cannot delete the images on those other albums :s only the photo album has the trash option...

hope theres something out there that can help me...

(i would prefer a non jailbreak option)

thanks
