Re: App download stuck on 'waiting'
I know this tread is a bit old, but i experienced the same last week and i wanted to help future people resolve this.
So what i did was synced with itunes, and from the apps section of the iphone page in itunes i tried to install an app that was in 'waiting'.
it then notified me that it could not complete because the computer was not authorized to, and all the 'waiting' apps disappeared from my phone.
clicked on store - authorize this computer ( up top ) and it said it already did...
anyway when i then synced again all the waiting apps reappeared and started downloading right away.
hope this helps someone
kind regards, Kenneth
