We'll say it up front: This is not a Windows phone. We agree with PhoneArena, which spotted this T-Mobile-bound phone on Samsung's Web site. When you click to get more info on the TouchWiz interface, which we WinMo fans know from the Samsung Omnia, you're greeted with an obvious render of TouchWiz running on top of Windows Mobile. Again, just like the Omnia.
OK, it's possible they're making a WinMo version of the Behold. But we're not betting on it. Likely this is just a bad Photoshop job (hey, we're all guilty of those) and not a new Samsung phone coming our way. Move along, folks. But if you still need more proof, peep the video after the break.
