Shopping for a smartphone that runs on AT&T's network? These models should be at the top of your list.
AT&T is no longer the exclusive carrier of the iPhone, but the iPhone remains AT&T's crown jewel. With its solid design, incredible ease of use, and all those apps, the iPhone 4 tops AT&T's lineup.
With its dual-core processor and the ability to run desktop-like apps, the Motorola Atrix 4G is almost more PC than it is smartphone. Add in support for AT&T's speedy HSPA+ network, and you see why this phone earns a spot on this list.
The Samsung Infuse 4G sports one of the biggest displays yet on a smartphone, measuring a whopping 4.5 inches diagonally. It also features a super-slim profile, version 2.2 of the Android OS, and support for sideloading of apps. And that's not all: the Infuse 4G is AT&T's first HSPDA Category 14 phone, which means it can deliver faster data speeds than the carrier's other 4G phones.
You don't have to shell out big bucks to get a top-notch cell phone. The HTC Inspire 4G is available for less than $100 on contract, yet still offers plenty of features. You get the Android OS, 4G support, and an 8-megapixel camera, for starters.
The Samsung Focus was the first Windows Phone 7 device launched in the U.S., and while phones running Microsoft's software don't get a lot of attention, this one is worth a look. It features a 1-GHz processor, a 5-megapixel camera, and 4.3-inch touch screen.
