| The Bottom Line | Although we weren't terribly impressed by the call quality or the form factor, the Cingular 8100 series provides powerful tools to the mobile professional for getting work done on the go. | For the ultimate road warrior, the 3G-enabled AT&T 8525 provides the speed, the power, and the productivity tools to get your work done on the go. | The AT&T Tilt promises to be the carrier's most powerful smartphone for business users with its full range of wireless options, Windows Mobile 6, and innovative tilt screen. | Even though the Pantech Duo has an impressive feature set that include 3G/HSDPA support, we were ultimately disappointed with its subpar design. | Although the Samsung BlackJack II doesn't bring any revolutionary upgrades, there are a number of welcome additions, including GPS and better performance, to make it a worthy successor and a good-value smartphone. |
