Nokia says they have something "big" coming up in their next event on the 5th of September, could this be it?

@evleaks is at it again. The random Twitter account which leaked the unknown HTC tablet has now leaked a new Nokia device, the Lumia 920. According to @evleaks it has a 4.5-inch display and has Pureview functionality, so it might have a crazy megapixel count like the Pureview 808.

There are no other details about the phone, but from the screenshots you can clearly see it's running a version of Windows Phone.
