Update – the following method is no longer said to be working but folks at phone pro user have found a way thanks to instructions laid down by xda developers which require a few more and different steps.

Basically, we will show our device as AT&T Lumia 635 which will be officially getting the Windows 10 Mobile. This process requires you to modify registry.

1. Install windows insider app on your windows phone. Ensure you are enrolled into windows insider program.
2. Open the insider app and login with your credentials. Make sure you use the ones you used for signing up for windows insider.
3. Download and extract the WPInsidersHacks app (from here) to your computer
5. Start the WPInsiderHacks app on pc, approve any firewall requests
6. Connect to the same WiFi that your PC is on. Edit the settings for the WiFi connection to turn on the Proxy and set it to use the PC’s IP address and enter 8877 for the port
7. Open Internet Explorer on your phone and navigate to http://[pc.ip.add.ress]:8877 where [pc.ip.add.ress] is the IP address of the PC running the WPInsidersHacks app
8. Tap on the link at the bottom to the fiddler root certificate
9. When prompted click open and then install to trust the cert and ok at the confirmation
10. Run the Windows Insider app and tap get preview builds
11. Tap on which custom action you’d like to perform. In my case I hit “Set to ATT Lumia 635” and click the arrow at the bottom
12. Accept the agreement and click the check mark at the bottom. the app will close
13. Now clear your proxy settings and run the insider app again
14. Tap get preview builds and login with your Microsoft account
15. Select the fast branch (if you’re reading this of course you want the fast branch) and click the arrow at the bottom
16. Go into the phone settings and check for updates. With any luck you should have Windows 10 there for you to install. On my AT&T 1520 it had to do 8.1 first but it kept going to 10 after 8.1 installed (had to check for updates again)
17. You’ll probably want to go into the settings and do another reset and then log into the phone and let it restore your previous data
