Epic 4G owner's everywhere are upset with their poor 3G speeds. Apparently upload speeds have been topping out at a less than spectacular 150kbps. While angry sprint customers everywhere flood Sprint's community forums, Sprint had this to say:
"We have heard reports of users experiencing less-than-expected 3G upload speeds with their Samsung Epic 4G. After extensive investigation, Sprint and Samsung have identified an enhancement that may improve upload speeds on the Epic. This fix will be made available in the next maintenance release. It's important to note that network speeds are impacted by many factors when using commercially-available speed test applications and test results may or may not be true indicator of the actual network performance."
So with that being said keep your pants on Epic owners Sprint and Samsung are aware and all over the matter.
