I predicted this. After iOS 12.1.1 was found to be cutting off cellular data for a number of users, I said Apple AAPL +1.28% would need to act quickly. Thankfully iOS 12.1.2 has now been rushed out for release. But does its short development time bring more problems than fixes? You might be surprised…
Here’s everything you need to know.
Who Is It For?
iOS 12.1.2 is compatible with all iOS 11 compatible devices. This means the iPhone 5S or later, iPad mini 2 or later and 6th generation iPod touch or later.
Compatible devices will be automatically prompted to upgrade but, if that doesn’t happen, you can manually trigger it by going to Settings > General > Software Update. Beta testers, you may need to unroll your device for iOS 12.1.2 to appear.
The new update weighs in at up to 85MB signalling it is a focused update. I say “up to” because different devices get different updates, so the update size will vary on different models of iPhone and iPad.
The Deal Breakers
First, the prerequisite warning to Jailbreakers: iOS 12.1.2 has not been cracked (neither have most iOS 12 releases prior to it) so stay away until your jailbreaking software of choice catches up. Right now, it looks like they’re fighting a losing battle.
