Just minutes after the rollout began, social media sites filled up with complaints from iPhone users who, after trying to download iOS 10 over WiFi, found that their iDevice had been rendered useless.

Apple has also recommended using AppleCare directly, or you can head over to an Apple Store if you don't have access to a Mac or PC.

iOS 10 is available now and works on the iPhone 5 and newer handsets. iPad Mini and newer models and the iPod touch 6th generation. They say that their devices are losing cellular signals and that the only way they're able to get cellular connectivity again is by restarting the device.

The major changes brought by the iOS 10 are most visible in the Apple Music redesign, Photos App, Messages, and Home App to name a few.

The early birds who updated their phones during the release day last Tuesday complained that the update bricked their phones. Before you download, it's also a good practice to make sure your device is backed up.

More recently, in February this year, Apple faced criticism after an update started bricking devices if they had been repaired by a company other than Apple.
