App Store won't let me download anything?

I tried to download a camera timer app, and the App Store wouldn't let me? My iOS is up to date and I have a iPhone 5c. At first I thought it was the app, but then I tried a couple of others, and when I pressed download it wouldn't work. I know the App Store had problems a day or two ago, but apparently they're fixed now? What's going on?

Press home button and power together wait apple logo to come and then let go off buttons wait till you come back to normal then try again

Try signing out and signing back in again.

AppStore was down, its back to normal now.

  • Why won't my iPhone let me download anything anymore? I have the iPhone 4s, and ever since I updated my software to the iOS 6.0, I can no longer download anything to my phone. No apps, no songs, movies, I can't download any of it. For example, when I try to download an app, I tap the price then it says, BUY APP in green. Then I tap BUY APP, and it says that it is installing for a couple seconds, and goes back to the price.
