If you are like me and decided to control what goes in and comes out from you ipod, read: manual sync for all items is checked. Then you might need to get the apps installed back to iTunes at some point. For instance, if you will be upgrading the firmware. It's pretty simple:

iTunes - Store - Authorize this computer
iTunes - File - Transfer purchases from XXXXX iPhone
