Here's mine. The background changes as the hours change. The earlier it is in the day, the brighter it gets and turns a bright blue. As it starts getting dark outside, it gets dark and changes to night. Pretty dope background, probably one of my favorites.

There is absolutely NOTHING wrong with jailbreaking a phone. It can't damage the phone, won't ruin it's integrity, or make it crash. If you have a problem with it, just restore it and that's it. Jailbreak just opens up the phone for ALL developers and their apps, not just the ones that Apple allows. I recommend it and i'm all about it
