definitely the Blackberry Bold. both phones are smart phones while the Samsung Epix has a touch screen and the Blackberry Bold doesn't. both the Blackberry Bold has a lot more to it, like the ability to be on the internet while you're on the phone. at least from what I've heard and I think I read about that on the internet. plus it's AT&T's best phone. so go with the best phone or a phone that's still pretty good and has a touch screen.
