This is really really nice, no more having to edit the DisplayOrder.plist file from your computer. Just download this app, play with the order from your phone, save and restart! To get iSBT on there, you can use the Installer.app if you've got it on there, or just download iBrickr, use the Browse Applications option, and you should be able to install it from there very easily.
EDIT: It's actually called rSBT.
