The Motorola i580 for Nextel is perhaps the best ruggedized do-it-all phone on the market. Built to the Military 810F spec, the Motorola i580 withstands dust, shock, vibration and blowing rain � so you know you can count on it! And within that super-tough exterior is some of the best mobile technology, including a 1.3 Megapixel camera, Bluetooth, three kinds of Nextel walkie-talkie and advanced voice dialing. With all this, the Motorola i580 is a workhouse cell phone unlike any other.
