Reddit user ChinaMan28 purchased a Lumia 920 off eBay only to find that it was running a unique operating system.
"Its got a bunch of weird apps, has data sense, I can close background tasks, here beta blue, seems it was someone who worked on the main campus got his phone lost."
He has since posted screenshots of the OS to Flickr which reveal a notification center, a redesigned calendar interface, multitasking improvements, and numerous applications that start with 'z'.
The software is version 12084.WPMAIN(wpbldlab).20130509-1407 which was compiled on May 9th. The Verge has confirmed that it is a legitimate version of Windows Phone Blue.
Apple debuted its notification center for iOS 5 in October 2011. It was added to OS X Mountain Lion in July 2012. Although, it's been available on iOS for quite some time, many hope Apple will announce improvements to Notification Center with iOS 7.
