My App Store opens, but when I go to download anything, the download just times out. I even see the app appear on my home screen with the "Waiting..." title, but suddenly it disappears. Has happened with many different apps, so it seems to be more than a third-party issue.
I had the same problem, until I opened another app (Maps), which accessed the App Store with recommendatons for public transport apps. Now I can connect normally to the App Store and download stuff. Hope this helps.
Ok i have got it working. Have to go to settings>itunes &App store and sign in with aple id. Hard reboot the iphone. Hold the power and home buttons the same time till you see the apple logo release the buttons and wait for phone to restart self.
