How to Download?
Now the question is should we download and install this beta version on our devices or not. The simple answer is it all depends on your purpose. If you are a developer and want to test your applications on iOS 9.3, you should grab it and run it on your devices. However, if you are a common user, there is little reason to bother at this point in time as the product is coming out in next week.
If you are first time installer of iOS 9.3, you’ll have to download it either from Apple Developer Portal or from Public Beta Program site. In case you are already running the earlier beta of iOS 9.3, you are required to use the built-in Software Update feature which is rested under Settings.app > General.
