I was another pissed Epic 4G user as well until... I rooted my phone, I rooted the hell out of it! I was so damn tired of Samsung's excuses and I just said hell with the warranty. I used the TrulyEpic Rom with Froyo and the ext4 file system. It's lightning fast, extremely stable and suddenly my GPS actually works! If it can take one man to modify a beta 2.2 release (DK28) to this level of stability, Samsung is purposely and deliberately dragging ass. Android phones were meant to be rooted and used to their full potential.
