Today at some point my Categories app decided to spit out all the icons back to the desktop. I restarted the phone, and it's still the same. I went to the Categories app and it's showing that all the apps are still in their folders....??? It looks like it duplicated all of the app icons and put them back on the desktop... EDIT=looks like it was an issue with Poof. Got it sorted out. Thanks for all the replies!
