Apple Preparing iOS 17.2.1 Update for iPhone

Apple appears to be internally testing an iOS 17.2.1 update for the iPhone, based on evidence of the software in our website's analytics logs this week.

General iOS 17 Feature Orange Purple
Our logs have revealed the existence of several iOS 17 versions before Apple released them, including iOS 17.0.3, iOS 17.1.1, and iOS 17.1.2.

iOS 17.2.1 would likely be a minor update with fixes for bugs and/or security vulnerabilities. Following the release of iOS 17.2 last week, some users have complained about a bug that causes the Messages app to disappear when rearranging app icons on the Home Screen, but it is unclear if iOS 17.2.1 would address this issue.

Given there are multiple holidays over the next few weeks, it is possible that iOS 17.2.1 will not be released until next month, although the update could be expedited if there are critical fixes. There was no iOS 16.2.1 update for precedent, but Apple released iOS 15.2.1 with a HomeKit security fix in mid-January in 2022.

iOS 17.2.1 would be a stopgap while Apple continues to test a larger iOS 17.3 update, which features a new Stolen Device Protection security option and re-enables the ability to create collaborative Apple Music playlists.

I feel Apple could possibly release this tomorrow or the day after to accommodate for the Apple Watch ban.

I hope they do. Honestly, I had very few issues with all the iOS 17 builds, but whew 17.2 gave me all the issues that others had complained about in the past. Overheating, weird WiFi, terrible connection handling, crap battery life, you name it.

I always install via IPSWs/Finder and I have a 15 Pro. Usually I don’t have problems, but 17.2 feels like an actual beta build for me.

Has Apple given up on ‘Rapid Security Response’? or has it been regulated to just a “OMG” moment where they need to have 99% of devices updated within 24 hours?

I don’t think we’ve had one in like 9 months or so… and I’m pretty sure it had problems for a lot of people.

Exactly what I was thinking. Sorry everyone sensor has been deactivated until further notice…
They won’t do that to current S9 and U2 owners.
