| The Bottom Line | 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 Nokia Lumia 900's unique design and high-end features make Windows Phone look fantastic, and the $99 price is extremely fair. Despite some flaws, this is my favorite Windows Phone yet. | 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. | 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. | Quad-core processing isn't everything, and AT&T's new $199.99 HTC One X proves it. This advanced Android has style, speed, blazing 4G, and power galore. |
