Windows Phone 8.1 / Lumia Cyan for devices with Developer Preview – Bit Locker Problem still consisting
Yesterday Greg Sullivan tweeted, that the final Windows Phone 8.1 / Lumia Cyan Update will now be available for some devices which have installed the Windows Phone 8.1 Developer Preview, the Nokia Lumia 1020 and Nokia Lumia 1520 on AT&T, and also the Nokia Lumia 920 on T-Mobile Germany.
The Update has not been available for devices with the Developer Preview installed until now because of the Bit Locker problem.

However update at your own risk, like you can see at the tweet below, some people are still experiencing problems with it, although Andy & Lenny from our site both updated successfully with no issues right from WP 8.1 preview.
@WinPhoneSupport I just updated my 1020 to Cyan from a Preview for Developer build and now my phone is on the BitLocker recovery screen.
