Which phone does OT prefer? The w580i is free. The shine is $50 after rebate. The shine feels a little more sturdy, but the sony supposedly has a little better reception. I know the buttons crack in the 580, but that's the only negative I've really heard. I'm looking for something that works as a good mp3 player and possibly a movie player. Camera quality isn't so important. Which do you think would be more water resistant? I'm a cyclist and I sweat a lot. I don't want the phone to get water damage. Thanks!
