Ok... I've been a Sprint customer for some time now. I know this is no fault of their own... But the Samsung Epic 4G has let me down. My wife has the HTC EVO and I just recieved the Epic two days ago. The initial problem was with setting up app's. It (Epic) kept telling me I had to be a Sprint user...??? The fallowing day I was dropping texts and calls? Today I took the two phones, sat them side by side and witnessed no connectivity on the Samsung, while the HTC had at least 2-3 bars and was running fine.. Do I need a Phone that does not, first and foremost work as one ( a communication divice)???
