Samsung EPIC 4G
The Samsung EPIC 4G is Sprint's specially branded version of the Samsung Galaxy S. Samsung announced all their Galaxy S devices simultaneously, and the EPIC 4G has several unique features and capabilities that help it stand out from its brethren.
Unlike the other Galaxy S versions, the EPIC 4G takes advantage of Sprint's ever-growing 4G WiMAX network, which is why it's got that "4G" tacked onto the end of its name. Other differences include a 5-row QWERTY hardware slide-out keyboard and an LED flash to go with its 5MP camera. Unfortunately the EPIC 4G only has 1GB of internal memory as opposed to the 16GB included in the T-Mobile and AT&T variants.
