Motorola's i530 (Nextel) is the Hummer of cell phones. With military-grade resistance to shock and dust, it's ugly, bulky, and ideal for users who spend more time off-road than in the office. Nextel has made its mark with sturdy phones, and the i530's design is on a par with that of the bulkier but equally sturdy Nextel i700. Although the Motorola-made handset isn't bereft of features--it includes Web and e-mail access--this phone is intended for active users who need a tough mobile for use in any kind of conditions.Though its unique look gives it the ability to take a beating, the Nextel i530 won't win any beauty contests. The black, rubberized flip phone measures 3.6 by 2.0 by 1.1 inches and weighs 5.2 ounces, which makes it bulkier and heavier than most candy bar-style mobiles. In short, this handset is more likely to be worn on a belt clip than slipped into a pocket. The Nextel is available in basic black and bright yellow.
