LO, it sounds to me that you aren't actually connected to the app store.
Tap the app once on the phone and see if it pauses or doesn't do anything.
On itunes remove it and make sure to 'delete' it from the itunes library if it doesn't already do that. Redownload it from the app store and it shouldn't come up pending then plug the phone in. Hopefully that should work.
Nope.
