re: iOS 7 Jailbreak Release and Info Thread (Apps/Tweaks/Themes in OP)

Cosmetic tweaks that change the look of the phone. Performance tweaks that can speed up your phone. Convenience tweaks that make some of the things in the stock iOS less annoying. Read the tweak descriptions in the OP. BiteSMS (still in beta) is worth it by itself. It's a texting app that replaces the stock one. When you get a text, you can reply from the text window without closing safari or a game or whatever you were doing. You can reply right from the lock screen as well.

You can add themes that completely change your phone. I can find screenshots of old themes if you need an idea as to what I mean.
