iOS 8.4 Update Fixes Text Message Bug Causing iPhones to Restart

The bug had been around since iOS 6, but its impact was minor; very few people knew it even existed. The iPhone text message bug was promulgated by a simple post on Reddit, and subsequently spread like wildfire across the Interwebs — and probably sent to your own iPhone, causing it to restart. A vulnerability allowed anyone to restart iPhones by sending a text message with a specific series of Unicode characters. Apple has finally rolled out a security update with the release of iOS 8.4, fixing the bug, as well as a wide range of other issues affecting iOS devices.

iOS 8.4 is available for: iPhone 4s and later, iPod touch (5th generation) and later, and iPad 2 and later.

Apple’s software update describes all the new improvements and features added, including fixes for the bug causing iPhones to restart:

If you’re worried about the security of your iOS mobile devices, we encourage you to update to Apple’s iOS 8.4. If you own an iPhone 4 and cannot update to the latest iOS version (iOS 7 is the last update iPhone 4 users can receive), now is a great time to upgrade to a newer iPhone and boost your mobile security.

iPhone, iPod and iPad users can get the latest update directly on the iOS devices (Settings > General > Software Update), or it can be downloaded and installed in iTunes when the iOS device is connected to a computer with an Internet connection.
