Successor to the popular BlackJack and BlackJack II, JACK is a perfect fit for business types. Featuring a full QWERTY keyboard, Wi-Fi, and the Windows Mobile 6.1 operating system, JACK is your own personal assistant in a sleek, stylish package. Users can view and edit business documents via Office Mobile which includes Word, Excel, and Powerpoint Mobile and when you're done, send emails and documents in an instant on the 3G network. Contacts, emails, calendars, and tasks are synched up using "over-the-air synchronization." Windows Mobile also enables simpler texting with threaded SMS. And if you're on travel in an unfamiliar city, the built-in GPS will keep you on the right path.

But JACK knows that all work and no play makes him a dull phone, so it also includes a 3.2 megapixel camera with video-capture capabilities so you can watch that funny video of your boss at last year's Holiday party. You can also listen to your favorite tunes with Windows Media Player 10. The memory is expandable up to 4GB so there's enough room to carry all your mood music. Windows Live Messenger is also part of the package so you can chat with friends when you're taking some downtime. And it just wouldn't be an exercise in goofing off without access to Facebook.

AT&T is retailing the JACK for $99.99 with a two-year contract. A combination of business, pleasure, and utility, the latest iteration of the BlackJack series is a device that shouldn't be overlooked. It is, for all intensive purposes, a jack of all trades.
