Go to the settings -> app store and re-enter your apple ID & password. Hope this will reset the app store and you will be able to access it.

  • IPhone App Store Update page not working? I'm currently iOS 6.0.1 (iPhone 4S) and when I go to the App Store I see the Updates sign but no "All Purchases" button. What do I do?
  • IPhone App Store not working? Unable to download? It says updates are available but when I try and download them they all say that they're loading, then clear, and then say "Waiting" and then an error message pops up saying "Unable to Download Application" and to retry. I hit retry and it does the same thing all over again. I've logged off and then back on, and turned my phone on and off and it still won't work. Is it just me? Or any suggestions?

  • How to switch from US App Store back to Canadian App Store on iPhone? I clicked somewhere by accident and got into the US App Store. Now I can't do any updates or download any new apps until I get back to the Canadian one, but there doesn't seem to be a setting to change for this.
