Back to Windows Phone 8 After a Long Love Affair with Apple and Android!!!

Install the Preview for Developers App from the WindowsPhone store. If a beta is available, it will prompt you, of course your 1520 warranty will be voided:-)

Welcome back. I got an N4 for my travels, my work travel app sucks on WP - so that I can rebook flights/hotel quickly if things change while I am on the road. I played with the N4 a bit last night and decided I am going to use it only while I am on the road, for daily use it is going to be the Lumia 810. Even though my daily driver did not get Lumia Black, I have Preview for Developers so I have about 90% of the Lumia Black features on it.

...but, when the full version drops, install it and delete the developers app. your carrier will be none the wiser.
