It pains me to post another one of these rumored release dates for the Samsung EPIC 4G. At first it was getting around that the Epic 4G could get a release on August 11th, though that date is proving unlikely considering no announcement has come from Sprint. The latest date getting tossed around is August 21st, only coming as word from a source with no corroborating evidence.
Take this more as confirmation that you will have to wait a bit longer to get your hands on the full hardware QWERTY keyboard of the Epic 4G and less a reason to get your hopes up. We will file the August 21st release date among the biggest of rumors.
