I got an iPhone 4s last spring and my storage keeps saying its full. I really don't have that much on my iphone. Under settings I looked up the Usage and it says all 13.5 available gigs have been used up. I plugged in my phone to my laptop and brought up iTunes. I discovered I have 11.3 GB full of "other" storage. WHAT COULD POSSIBLY TAKE UP 11 GBS!
