Set to launch later this month, Sprint’s version of the Samsung GALAXY S II smartphone is now available for pre-order from popular cell phone retailer Wirefly. While the highly anticipated Samsung Epic 4G Touch is set to launch at $199.99 from Sprint, Wirefly is offering early adopters an unusual discount — a pre-payment of $149.99 will secure anxious GALAXY fans an Epic 4G Touch as soon as they become available in mid-September. Announced late last month at a Samsung press event, Sprint’s Epic 4G Touch features a 4.52-inch Super AMOLED Plus display, a dual-core 1.2GHz processor, 16GB of storage, an 8-megapixel rear camera, a 2-megapixel front-facing camera and compatibility with Sprint’s 4G WiMAX network. The sleek smartphone will launch nationwide on September 16th, though the Wirefly site does not specify when pre-orders will ship.
