It takes too long to sync all my iPhone apps to my PC, and I don't even need to have my iPhone apps saved to my PC. So I want to uncheck the "Sync applications" box in iTunes, but then I get a popup saying "Are you sure you do not want to sync applications? All existing applications and their data on the iPhone will be removed." Why is it going to delete all the apps off my iPhone if I uncheck that box? I just don't want it to sync the apps.
