This morning, I was at Sprint store to test out Epic 4G before I commit 2 year contract to it. While playing with it, I realized that compare to the EVO 4G right next to it, the Epic has a much slower upload as well as download speed on 3G network. With Epic, I only got 200k bit/s down and about 100+k bit/s upload speed. While on EVO, I could get 1+ Meg bit/s download and 700+k bit/s upload. This result was consistent for all epic units that I played with. Another problem for this problem filled device. This is a shame for such a nice device.
