I don't want to re-jailbreak each time, I find that the only real use I get out of it is SBsettings, but that's a big use. Are there any real apps that emulate it?
I wish. SBsettings is also probably the biggest reason I jailbreak also. Unless Apple allows for some radical changes to their app store you wont see an app like that in there ever.
It would be impossible for anything in the app store to do that, since it requires the ability to adjust brightness, hardware settings and play outside of the application sandbox.
