Yea same here, I am constantly on my phone all day tweaking and changing things, but it's what I like to do, and jailbreak gives me that option, if you want just a phone don' t jailbreak
Just did that But I did not use a theme I added five folders in my dock and rename them added a fifth row and sort all the apps because I have a lot of apps, now I have a clear view of all my wallpaper, use boss paper changes every 5 seconds awesome
recently had this problem, iphone4 jailbreak 4.3.2, on the right of the clock there should be a lock with a circle, double tap the home button, scroll to your left, click to unlock, press the home button once, all done.
