Apple's new iOS 12 beta image is out and there are a few interesting features already. One notable thing is that Apple seems to be pushing towards 64-bit devices because it has not provided a restore image for 32-bit devices with this beta release. Let's take a look at some of the other changes:
What's New in iOS 12
Here are some of the improvements and bug fixes that can be found in iOS 12, according to the release notes:
- Fixes problems with SiriKit car commands.
- Fixes problems with VPN services from third parties.
- Appears to offer these improvements for 64-bit devices only. (More on that below.)
The Release of iOS 12
The main surprise of iOS 12's release is that it is so far only available to 64-bit devices. This seems to heavily imply that Apple will be cutting off support for several iPhones in the middle of their generational cycle, and ending its support for all 32-bit devices. For many people who bought the iPhone 5 or iPhone 5C, this can come as an unwelcome surprise. Unless Apple restores support to 32-bit devices, those with older iPhones might find themselves having to upgrade very soon.

How to Downgrade from iOS 12
Downgrading from iOS 12 to an earlier version is inadvisable, since this version comes with a new file system. However, you can downgrade from iOS 12 beta to one of the stable versions a bit more easily, like iOS 11. Here is how to do it:
- First back up your iPhone. If you're unsure how to do this, look at the instructions above to make an archived, encrypted backup.
- Download (to your PC) the previous version of iOS. Do this by downloading the restore image for the version you want to downgrade to on ipsw.me.
- Plug your device into your PC.
- Open iTunes.
- Click on your device to get to the device summary page. (Make sure you turn off "Find My iPhone" on your device.)
- Hold Shift (on Windows) or Alt (on Mac) while clicking on "Restore iPhone."
- Browse to find the ipsw image that you downloaded in Step 2.
- Click "Open," then "Restore."
Now you should have a device restored to this previous iOS version. It will also be blank of any data.
If you worry about the security of your iPhone data in iOS 12, you can consider permanently delete unwanted private data from your iPhone. Deleted data by iMyFone Umate Pro is 100% unrecoverable.
