I know how to upgrade or downgrade the OS from an older one to a newer one or vice versa, but how about reinstalling the software that you already have? I think that may fix a couple problems I have (Facebook's Friend Finder not working correctly, Blackberry Messenger bugs, etc.).

Anyone know how to do this?

If you already have your current OS installed on your PC, wipe your device with JLCommander and reload it just as you would with an upgrade or downgrade (Don't forget to do a backup first!)
