Windows Phone GDR2 update begins its roll out

Turns out that unlocked HTC 8X have started joining in onto Sammy's fun earlier today, which likely confirms that the roll out is already under way.
- A new Data Sense feature that will help you track your data consumption
- FM Radio
- You can now set a Camera app of your choice
- VoIP apps like Skype and Lync feature improved stability and performance
- HTML5 improvements
- Other, undisclosed tweaks
You'll probably arrive at the same conclusion that we did: these are all relatively minor. Fortunately, the GDR3 update, also known as Windows Phone Blue, will bring features of a significant importance in comparison. Apart from support for 1080p devices, WP Blue is expected to introduce huge changes such as a new notification center, better multitasking and unknown changes to native Windows Phone apps.
As always, once it's official, you'll be among the first to know.
