Just yesterday (all Apps opened for one second then closed?! Restarting Apps and reboot of iPad was no help) I have read older threads where this occurred like 2012, but is this STILL not fixed (iOS 8.3) !? -- Answer was to find a WiFi connection and reenter the Apple ID. So... does this mean if we have no Internet connection (like an overseas flight or remote country) our iPads can become just a paper weight, and completely useless!? Is there no way to clear this problem otherwise?
