Hello all, Just ordered an Epic 4G a piece for my wife and I through our sponsor. We are both super excited, but I fear we'll be a bit in over our heads. We both come from non-smart phones (currently, me - Samsung Gravity, her Nokia xpressmusic 5310, before that, we had Motorola RAZR's and Motorola V300's. I've done a lot of research on android and I'm super excited to join the crowd. Any suggestions for "can't live without" apps to start out with?
