Interesting as I just 'flashed' to a new Samsung 6.1 Maintenance Release_Upgrade ROM (full 92MB file .exe)...
I then D/L the Bing.cab (standard version for 6.1 and 6.5 devices) from their site, and stated that 'it doesn't recognize my device....but you can try it anyway'....link
I installed it to my storage card, and here is the results:
Bing Mobile Version: 5.1.2010.3290
(available update--->is now properly grayed out)
Different Homescreen GUI
Haven't had time to 'play_with_it' much for testing purposes, but will report back here with my findings...
