In a little more than a year since it was released, the iPhone has put the cell phone industry -- and designers -- in a spin. Some would call it a spinoff, with some phones being iPhone knockoffs, and more coming in the weeks and months ahead. The most obvious look-alike iPhone feature these phones share is the touchscreen.
Some of the phones also include slide-out keyboards for those who prefer that option. The iPhone, though, is the only one that has Apple's software, one of the device's biggest benefits because of its ease of use. But because the iPhone is only sold in the U.S. by AT&T Wireless, if you're not an AT&T fan, you might prefer some of these similar kinds of phones offered by other carriers.
