I have 2.60 GB of data labeled as OTHER on my iPhone 4S, how can i find out what exactly this is, because i have no clue. What should i do to try to to remove it all? (i know you can't remove all of it, but at least get a chunk off) i deleted my messages i think that helped a little, and for those who will ask, my iPhone IS NOT and has NEVER been jailbroken.

That is probably the amount of data that is need to actually makes your phone work. And no don't delete it.
