Today Samsung and AT&T announced the Jack, successor to the BlackJack series of Windows Mobile devices. The Jack is a bar-style phone with full QWERTY keyboard, 3.2 megapixel camera with video capture, Wi-Fi, GPS and 3G. It has a microSD slot and supports cards up to 16GB. The Jack will run Windows Mobile Smartphone Edition out of the box, but can be upgraded to Windows Mobile 6.5 once the new operating system becomes available. The Jack will go on sale May 19, for $100 after rebate with new two-year agreement.
