Fix For Annoying ‘Unable to Purchase’ Error on iPhone

Been having an error popup evrytime I hit the “Update All” button in the App Store on iPhone. Found a very helpful article on apprelated.com with an easy fix for the issue. With the help of extremely easy to use iExplorer the issue was fixed in about a minute. Restarted the App Store and the error was gone, I can now press “Update All” in peace.
