iPhone 4 Storage Disappearing I have a 16GB iPhone 4 running iOS 7. In Settings > Usage > Storage, it says I'm using 13.3 GB and have 240 MB left, but I added up all of the space the apps/their data take up and it comes to 9GB (and thats rounding up!).

I listen to and download a lot of podcasts and for the last few months I've been sitting at ~1GB of free space, with the podcast app having trouble downloading anything after there's less than 600MB free. Over the last day though, I've been downloading a bunch of podcasts that fail to download, but take up space. For example, I had ~400MB and tried to download a ~100MB podcast. It failed but in settings it says I now have ~300MB of free space.

I've looked around for answers online, but I couldn't find anything that seemed to relate. I've tried turning it on and off again a bunch but that didn't help.

Has anyone else had this problem? Is there an easy solution?

Thanks in advance.
The hard-reset and all that didn't work. I re-synched it to a different computer. It got rid of half of the Other storage, so I guess it worked. I'm not sure it's really a good solution, but whatever.
