AT&T

It was love at first sight: From the moment I unboxed the HTC One X ($200 with a new two-year contract on AT&T; price as of as of 5/1/2012) I immediately fell for its slim profile and brilliant 4.7-inch display. But it was more than just the phone's good looks that snagged my heart, as the HTC One X came with a tasty serving of Ice Cream Sandwich (Android 4) and a long enough battery life to keep me satisfied for hours on end. But like all romances, this one was not without its sour spots, and even the One X's smoking-fast LTE connectivity was not enough for me to overlook the phone's poor call quality and its clunky HTC Sense overlay running over Android.

Shopping for a cell phone can be overwhelming; after all, these devices do a whole lot more than just make phone calls. They also come in a variety of shapes, sizes, prices, operating systems, and user interfaces. So which carrier has the best selection of phones? It really depends on what you're looking for.
