Samsung and AT&T have been hard at work to bring the Windows Mobile 6.5 Standard upgrade to the Samsung Jack, which operates on Microsoft’s non-touchscreen operating system. The Samsung Jack for AT&T is said to now include the following new features:

Windows Marketplace for Mobile: Discover apps that unlock the power of your Windows Phone, shop securely with confidence, and download instantly to your phone.

-Internet Explorer Mobile: Internet Explorer Mobile 6 delivers the same high quality browsing and media viewing experience that you’ve come to expect on your desktop computer. If you can see it in Internet Explorer on your PC, you’ll be able to see it just as well on your Windows Pphone, whether the content you want is on YouTube, a game using Flash animation, or on a social site like Facebook or MySpace.

-AT&T WiFi: Automatic access to over 20,000 AT&T Wi-Fi Hot Spots nationwide is available on the Samsung Jack and is included in select smartphone data plans. This allows for fast and easy downloads of your favorite music, streaming videos, games, and more.

-Vlingo for Windows Phone: Instantly send a text or email message, call a friend, search the Web, open native applications and more, all by speaking into your Samsung Jack Windows Phone.

I am traveling through the end of this week. We’ll give you a video tour of the Jack with Windows Mobile 6.5 next week. For now, if you do own a Jack and want to hop in on the updated OS, you can check out Samsung’s upgrade portal.
