The lucky owner who purchased the Lumia 920 with Windows Phone 8 GDR3 and the new Bittersweet shimmer firmware from Nokia, has put the device up for grabs on eBay.

It was just over the weekend that forum member xs2k posted in the Windows Phone Central Forums screenshots of the next version of Windows Phone 8, expected in November. Featuring Driving Mode, ‘X’ to close out apps, screen rotation lock and enhanced Bluetooth, GDR3 will also allow for new 1080P resolutions and advanced Qualcomm chipset support.

In a series of posts and later videos, xs2k demonstrated how many of the new features worked and also confirmed the legitimacy of the information. Now you can own a piece of history by picking up the device, which is currently on an open bid with just under three-days left. The current price is $102 though that will certainly go up once more people become aware of the auction.

The device is a matte black and unlocked AT&T Lumia 920, so it should work well on that network’s LTE bands. Being a beta build of the OS and firmware, it’s not clear how stable the device is for everyday use nor the prospects for updating it in the future.

Windows Phone Central has verified that the device listed is by the same poster in our forums.

Head to the eBay listing (while it remains up) to make an offer, if you have the cash.
