We know you are looking to download iOS 11.2 Beta without a developer account. Here's how you can do just that.
iOS 11.2 Public Beta Will Arrive Soon. But You Can Take iOS 11.2 Beta 1 for a Spin Earlier.
iOS 11.2 Beta 1 has been seeded to registered developers, and the final version of iOS 11.1 is not even out yet for the end user. There's no doubt in the fact that Apple is rapidly working in the background to fix things up when it comes to iOS 11, and the testing just can not stop.
If you are excited about iOS 11.2, then you are definitely looking forward to trying it out. But sadly, the pubic beta is not out yet, and your second option is to download the developer beta for free, that too without an Apple developer program account.
All it takes is downloading an iOS beta software profile and you are good to go. Once downloaded, you'll be prompted to restart your device, and the iOS 11.2 Beta 1 update will be available to download over the air. You can initiate the download by heading over to Settings > General > Software Update.
But wait, where do I get the iOS beta software profile from? Glad you asked, because we've covered the download process before as well. So all you have to do is head over to this post and download the profile onto your device. But be warned, should anything go wrong, we will not be held responsible at all. Therefore it would be wise to backup everything using iCloud or iTunes on your device before proceeding with the update process.
It would be irresponsible to conceal facts, but there's no doubt that there are many things that can go wrong during this process. There is a chance that Apple might block this method of installation once and for all leaving you in complete limbo, forcing you to restore your device using iTunes. But hey, if you are going to take risks, then it's best to take into account the risks involved in such things.
