I'm sure there's already posts on this, but I can't get a single music player to work on beta 2 iPhone 4. I was able to use Sirius no problem on beta 1, but now that, along with pandora or stock iPod player crashes. When I can get iPod to play, it's very patchy like a badly scratched cd. And no, it's not because I should expect this on 3 year old hardware. If it can play youtube and videos just fine, it should play music even better!
