Microsoft forgets Windows Phone Prototype in bus - Whoops !

An employee of Microsoft forgot or dropped his Windows Phone Prototype in a bus, new Windows Phone screenshots, notification center, UI changes, and more leak after a person sold the phone on eBay. The company is testing early future versions of Windows Phone with this feature in place. A Reddit user has posted a series of screenshots from a recently purchased Lumia 920 that appear to include an internal Windows Phone build. The software identifies itself as version 12084.WPMAIN(wpbldlab).20130509-1407, meaning it was compiled on May 9th. An early notification center can be seen in one of the screenshots, providing access to the typical Live Tile notifications.

Microsoft regularly includes these apps with developer units, so it's not unusual to see such applications on early builds of software.

One particular application, Here Drive, mentions "beta BLUE" at the end of its name. It's not clear if the Blue moniker refers to a rumored Windows Phone "Blue" update, but the features and changes would indicate that this is a future version of Windows Phone. The screenshots could all be an elaborate hoax, but they're consistent with what we'd expect early versions of Windows Phone to look like.
