The newest Windows Phone from the Nokia camp waiting to become available over in the States is of course the Nokia Lumia 900, and if the rumours turn out to be spot on we should see AT&T launch the Lumia 900in roughly two weeks time. So for those that are patiently waiting for the AT&T Nokia Lumia 900 to arrive, we have a couple of videos of the handset for your viewing consideration below.

The first video is an unboxing of the Nokia Lumia 900 for AT&T along with some first impressions, while the second video delivers a nice ten minute showcase of the Nokia Lumia 900 operating system, and both videos come our way courtesy of the guys over at Phone Arena and by way of YouTube user Tech Feed TV.

In the unboxing video we see that the packaging of the Nokia Lumia 900 has been kind of styled to match that of AT&T’s portfolio rather than Nokia, whilst inside the box you get the usual stuff such as a white microUSB cable, microSIM removal tool, the documentation and a somewhat unique round wall charger, although the AT&T Nokia Lumia 900 doesn’t actually come with any headphones.

In the OS walkthrough video we see the Windows Phone being taken through the process of being started up, along with setting up Windows Live ID, and taken through the interface along with numerous launches of apps, the Marketplace, people hub, and such.

Anyway, as I have no wish to spoil your viewing enjoyment, I’ll leave it right there and let you head on down to mash those play buttons and check out the Nokia Lumia 900 footage for yourself…enjoy.
