iOS 7.1.2 update won't download
I updated two iPhones to iOS 7.1.2, but on my iPad 2, it says "update requested... Your software update request has been received. You will be notified when the update has been downloaded and ready to install."
Every now and then it changes to "downloading...", but then changes back to "update requested...". It originally said "downloading..." when I tapped install, but never downloaded and changed to "update requested..."
i tried restarting, but that made no difference. I put it in airplane mode and turned Wifi off, but that didn't help either.
