On the market for an iPhone? Here's a breakdown of all the currently shipping iPhones from Apple.
Apple Releases iOS 11.2.1 Update With HomeKit Remote Sharing Fix
The iOS 11.2.1 update can be downloaded for free on all eligible devices over-the-air in the Settings app. To access the update, go to Settings --> General --> Software Update.
The iOS 11.2.1 update addresses bugs and issues that have been discovered since the release of iOS 11.2.
According to Apple's release notes, the update re-enables remote access for shared users of the Home app. Apple broke remote access for shared users when implementing a fix for a major HomeKit vulnerability last week.
The HomeKit bug allowed unauthorized access to HomeKit accessories that included smart locks, and it was fixed server-side by Apple after it was made public. To address the issue immediately, Apple had to disable remote access for shared users, which the company said it would re-enable through an iOS update this week.
Following today's update, the HomeKit vulnerability is fully patched and remote access for shared users has been reinstated.
