folder enhancer is pretty nice
Which one is the best? There are three that I can see. Free, 99¢, & $1.49.
My favorite is NoLock. I do not have to swipe to turn my ipad or iphone on. VERY cool. To me, this one app is the single main reason to JB. Apple should give us the option to swipe or not...it's a fundamental flaw IMHO.
Sbsettings, as others have mention, is indispensable, if only for the quick access to brightness. Also, to 2x tap the status bar to switch programs is critical to avoid using the annoying home button popper.
Infinidock is awesome.
MyWi - pretty obvious how important it is to share my signal with my other devices.
