What Exactly Is "Other" in iPhone 4?

[stoneland]

I couldn't find a thread on this topic (my search terms were too common and therefore omitted) and I've read that it could be calendar appointments, OS system files (which makes sense), emails, etc. Is there any way to see what it actually is? I ask because when I was on 4.3.5 my "Other" was smaller than it is now on 5.0. And interestingly, when I restored as new for my update, it was at the same size it was before, but it was yesterday all of a sudden that it jumped up (I believe it is 0.50 GB now, which isn't much but larger than what it used to be right when I first updated). Could it have something to do with an iCloud backup? That doesn't make sense because that's not stored on your phone, correct?

What is the size of your "Other"?

I'm at .79 GB, I think. It's your album artwork, text messages, calendar stuff, contacts, etc. I haven't deleted my texts in forever, so that's why mine has increased a bit.
