A tipster over at WPSauce sent them a screen shot of a Samsung Omnia 7 sporting WP7 version 7720, which is the RTM version of Mango.  We saw this same version number on the Mango-toting HTC Mazaa that was awarded to a student developer yesterday and is expected to be made available to current WP7 devices this fall.  File this one under "iffy," as the picture cannot be verified and no details have been provided for its context.

In fact, the closer we look at it, the more fake it looks.
