OK, let's not all lose our stuff there, but that indeed is Windows Mobile 6.5.x (or 6.5.3, if you prefer) running on Toshiba TG01 at CES this year. You know, the same TG01 that's been out for some time now. You can spot the upgraded OS by the round buttons at the bottom, and that the Windows Flag start menu has shifted south as well.
And the TG01 still isn't a slouch when it comes to hardware. It was the first WinMo phone to sport the 1GHz Snapdragon processor, its 4.1-inch (nearly as big as the HD2) touchscreen, while capacitive, is very good. And so long as it's not running that weird neon UI we saw on top of it initially, it's very snappy.
So we know the following: An updated version of Windows Mobile 6.5 is on the way for the TG01. This isn't some hacked ROM. (And for those of you counting at home, it's Build Windows Mobile 6.5 Build 23091.5.3.0. By comparison, the cooked ROM I'm running (find it here) is Build 28001.5.5.0. That's a whole different branch, and don't read too much into it. But suffice to say this isn't likely isn't the bleeding edge of Windows Mobile that we're seeing here. We've been running this on cooked ROMs for some time now.
That said, we learn the following: Windows mobile 6.5.3 indeed is coming to devices, and the TG01 likely will be one of the first. As for the rest? Start your guessing.
