Now you can call to confirm your reservation at Craftsteak while you check your e-mail -- and with a device that's slimmer than a deck of cards. At 0.46 inches thick, the Samsung BlackJack smart phone is slightly skinnier than the Motorola Q and works with Cingular's new high speed network, which lets you juggle phone calls and browse the Web at the same time.

The device, which runs on the Windows Mobile 5.0 operating system, makes it easy to stay in touch with Good Mobile Messaging or Microsoft's direct push e-mail, which are similar to RIM's BlackBerry technology. Unfortunately, dialing isn't so easy; the way the numbers are spread out on the keyboard is a bit awkward. But a handy thumbwheel does allow you to easily navigate menus and your in box. The BlackJack can fetch your e-mail at up to 800 kilobits per second.

The BlackJack also includes a 1.3-megapixel camera and speakerphone, and it can grab the latest CNN broadcasts using Cingular Video, should you choose to check in with the real world.
