As one of the largest authorized retailers for AT&T, Mobile Communications Systems equips conversers with phones, accessories, and services to fit various lifestyles. Requiring a two-year agreement for activation and upgrades, the plethora of impressive phones—including GoPhones, data phones, smart phones, and 4G phones—assures that talk meets its technological match. Smart phones, including the Samsung Captivate ($99), impersonate small computers with 16 GB of memory, a keyboard touch screen, and that new microprocessor smell. Built from recycled plastics, the Samsung Evergreen ($69.99) supports mp3 files and graces fingertips with a QWERTY keyboard. For more advanced technophiles, the 4G Motorola Atrix's ($199.99) 4" screen displays crisp videos powered by a dual core 1GHz processor, and the 4G HTC Inspire ($99.99) runs on Android 2.2 OS and records videos in 720 HD.
