Syncing Apps: How To Select All/Select None
By now most of you have probably accumulated a ton of apps, but you don’t want every one of them to sync to your iPhone. You have it set up the way you want it now, but if you restore or sync a new device, iTunes will try to sync every app you have.
So the easiest solution is likely to deselect all of the apps you have an manually select the ones you want synced. To do this, go to the applications sync tab in iTunes and command-click (control-click on Windows) the checkbox next to an app. This will tell iTunes to uncheck every app, not just the individual app you clicked on. From there you can check the apps you want. It works in reverse too, but for this example we’re assuming you don’t want to select them all. Enjoy!
