App Store will not let me download ANYTHING!
I just got an iPhone 4s. I am selling my old iPhone 4 to my friend. I figured i'd be a nice guy and update the phone to the latest software, and download some apps to save him the trouble, but when I open the App store I click on something thats FREE and it WILL NOT let me install the app. Like the button doesn't go from FREE to INSTALL APP. The tough screen works and there is nothing wrong with this phone what so ever. I've restored it on 5.1.1 three times, all a no go as it didn't fix the problem. I'm getting pretty frustrated as I had no issues using it as my personal phone. Any idea what is the problem? I need this to be resolved by Thursday.
Thanks
iPhone 4, iOS 5.1.1
