An hour??
Well If you use Holo Launcher (or others) you can backup your icon locations... Go into settings and look for it. Holo has both a "backup settings" and "backup desktop shortcuts". Once you have a solid backup of desktop shortcuts with all your icons the way you like them, then whenever you batch restore apps with TiBu, you then go into Holo and restore the icons where they were. I use Nova Launcher Prime myself and it has the same feature. I am sure most good launchers have this capability. Give it a whirl, I think you'll be pleased.
Thank you - I will try that next time
