If you’re a developer looking to take a peek at iOS 10.2.1, here’s how to install the developer beta.
Update February 20, 2017: Apple has just released iOS 10.3 beta 3 for developers. If you have a previous iOS 10 beta installed, you can head to Settings > General > Software Updates and get started downloading. Note that this update moves your device’s file system over to the Apple File System, making downgrading difficult. If you were waiting for beta 3 to get started with iOS 10.3 testing, keep reading and we’ll help you get set up.
iOS 10.2 is on its way with new features, several that require lots of third-party developer input. As such, the company is releasing developer betas so that software engineers can get a head start on making great software for you.
How to make an archived backup of your iPhone or iPad
Before you begin, make sure you back up your iPhone or iPad. While the beta process is fairly straight forward, any time you make any significant change to your device you risk problems.

(And enable Encrypted backup — it’s worth it!)Click on Back Up Now. (Click on Encrypt Backup and add a password — you want the security.)Back up Apps, if asked.
Press Command, to open Preferences. (Or go to iTunes in the menu bar and click on Preferences.Click on the Devices tab.Option-click on your Backup and choose Archive.
Archiving will prevent your current backup from being overwritten by an iOS 10 backup in the future, should you want to revert for any reason.
