Other iPhone category growing to half my total space?

The "other" category on my iphone 4 is now consuming about half of my 8gb. I don't know what it is or how to get rid of it. I do know that NONE of my apps are taking up alot of space and oi only have under 20 apps total… IPhoto doesn't have alot and neither does my music or videos. WHAT IS HAPPENEING?

Restore the phone to like new. Then just add the apps you wanna keep on it. It's happened to me. And that's what I did

If this is with a contract, more than likely its stuff installed by the company. Also most of the time, it is apps, but I know that on my sister's iPhone, before apps, 4 gigs was taken up and she has a contract with Verizon.

  • What is the other category on my iPhone storage? When I connect my iPhone to my computer I see nearly 5.0GB of "other" in the storage. I only have a 16 GB iPhone so it's clearly a problem. What is this "other" and how can I fix the issue?
  • What is in the Other category on my iPhone storage? I have an iPhone 4 (not 4s), and when i plug it into my computer, it says there's 3.5gb of Other, but i don't know what's in this "Other" category. I cleared all my web history/cache/cookies, and deleted tons and tons of emails along with all my text conversations and recent calls, but that barely did anything. What else can i do to reduce the size of this category?
  • What is in the other category on my iPhone 4S capacity? 3.5 gb of my phones capacity is being taken up by this others category and now my phone has no space. What is in it and how do I clear it?
