A kind tipster has sent us this picture of what we believe to be the Nokia RM 820, heading for AT&T.

The Windows Phone 8 handset, as can be seen from the flag, looks similar to the Nokia Lumia 900, but with an appreciably thinner profile. The screen is also flat, and it seems the charging port may be on the top of the handset.

If this is indeed the device I am pretty satisfied Nokia has done enough to move the Lumia 800/N9 design forward. Do our readers agree? Let us know below.

Update: It seems the picture is a high res render by Jonas-Daehnert. Hopefully the real device will look half as good.

Thanks 820 for the tip.
