The Samsung SGH i-937 has been appearing on the Bluetooth SIG which has started speculation that this is the Samsung Galaxy S II-the hottest smartphone currently known to man-but with Microsoft's mobile OS on board. Because it has the same exact profile as a Mango flavored Windows Phone 7 stack and has appeared on a list of Windows Phone 7 devices playing games from Occasional Gamers, it can be deduced that the SGH i-937 is a Windows Phone 7 powered handset. Add to this the fact that the model number is just 10 above the Samsung Galaxy S II, and you might have enough circumstantial evidence to start a decent rumor.
With the response that the Android powered Samsung Galaxy S II has received in the marketplace, it would be a good business decision to see if that success could be repeated with an OS that is looking for a jump start anyway. Of course, we wouldn't expect to see anything resembling a Galaxy S II with Windows Phone 7 running the show until after the Mango update takes the OS to the next level promised by the gang at Redmond.
