Having this problem on both my iPad3 and my iPhone 5c. Been happening since the 7.1.2 update, but it was happening earlier in that day as well. I have auto-update set up on both, and whenever it tries to update, the app gets greyed out and then I get the ever popular "Unable to Download Apps" message. I've tried: Closing all apps (both) resetting (both, holding down power and square until Apple sign) resetting to factory (iPhone only, not bothering with iPad since it didn't work) logging out and in of wifi and store accounts attempting from 3g (iPhone only) prayer What's even more annoying is that the problem started the day of the new iOS update, but it started before I updated, and the update worked fine. Any ideas?
