AT&T gets a bad rap. The whipping boy of cell providers. They are the only one who has the iPhone which makes them even more appealing to whip.
Anyway to the OP it has been known that the Epic 4G would have these extra features for a while now. I would agree with you that it doesn't make sense for the 4 listed above to not have a LED flash. The LED indicators I don't particularly like but I also see no reason why they should not have been included. As for the front facing camera...it is useless. I won't go into why as it has been stated many times before. So I guess the point of my post is why are you mad? Because you just found out about these other features missing from our phone and would have made the jump to sprint had you known otherwise? If so you should have done some research. I just don't see the point of this post except informing people who didn't know about the features of a phone they don't have.
