One of the greatest things about iOS is its amazing interface. One of the worst things for a lot of people about iOS is the lack of customizability in the interface. One of the few ways we are able to make our I-devices our own is through the images we use for our backgrounds. This app gives you options, pictures already matched and ready to download. It has a few quirks to how it actually works... but once you figure it out its pretty cool. Hate the pop up ads, though, but I understand their necessity.
