Gottobemobile posted a helpful table showing the various tasks involved in updating to the new iOS along with estimated times for each. The further behind you are, the more data there is to download for the upgrade. Your only option is the most current version, iOS 15.2.1. In December, these security updates were no longer available.

And if you’re running iOS 14, you can no longer update it with security patches despite Apple previously saying it would continue to support it.

If you didn’t update the iOS on your compatible device when 15 came out, now is the time to catch up. It’s important to note that fixes are cumulative. However, security fixes should take priority over most other issues. You should know that no problems have yet to be reported with the update, which is one thing we do want to check before updating an operating system or an app. If you were out of town, that could cause real problems with your connected smart devices. If the user restores the device and signs back into his or her iCloud account, the Home app will once again become unusable and the phone may become inoperable, resulting in a restore and crash loop. A hacker could take advantage of this problem in the software by sending a Home device invitation that would trigger the user’s Home app and phone to crash. It worked through default settings for HomeKit, Apple’s framework inside its Home app to find, connect and control smart home devices such as security cameras, doorbells, outlets and light bulbs. In August, a security researcher discovered a vulnerability in iOS 14.7 and later that could crash affected devices.
