There are several web based and paid apps that let you to create shortcuts in the home screen for frequently changed settings.

They replace SBsettings until a good (untethered) jailbreak solution is available for iOS 5.

With all web apps and a paid app I've tried you can insert one shortcut (icon) at a time.
One web app I've tried has a bundle that you can install 40 shortcuts at once. Who wants 40 shortcuts?

There is now a new FREE web app we more than 20 different settings shortcut to choose from that allow you to preselect the shortcuts you want and install all selected at a press of a button.
