Apple is pushing out iOS 6.0.2, a minor update that is said to provide a possible fix for Wi-Fi issues on the iPhone 5 and iPad mini, along with other bug fixes, but it’s proving hard for users to install.
Multiple reports on Twitter, elsewhere on the web, and among our own staff find that there’s a problem connecting to Apple’s update servers over the air from iOS devices.
The update can’t be found on a range of devices, according to users on the iPhone 4S, 4th generation iPad, iPad mini and iPhone 5, so it it looks like this could be a very widespread problem. Chances are it’ll be resolved on Apple’s side of things soon, enough, but since the update is a relatively small one specific to the iPad mini and iPhone 5, it might be worthwhile to just hold off for a little while to let everything settle down.
Alternatively, you can plug your device into your computer and download and install the update the old-fashioned way, via iTunes, which I can confirm works perfectly well even if you’re seeing the “Unable to Check for Update” error on your phone or tablet itself.
Update: It looks like many users are now able to get the update over-the-air. Here’s a sampling of reports from users having success:
