Just as Microsoft has promised, the update for Windows 10 Technical Preview for phones is now ready to be downloaded. Okay, so they are nearly an hour late due to server issues, but we can confirm that the update is NOW LIVE. At least for SOME phones (our Lumia 635, for example, is getting the update).
Users who are part of the Windows Insider program can now head to their device Setting > Phone Update and check for a new OS update. Make sure your phone is charged up and preferably you are on Wi-Fi to download the bits (the update is 450 MB).
