I decided to be a guinea pig for the release of 3.0, and upgraded around an hour or so ago. Everything went smooth, no issues, just ran the update through iTunes. So far, I'm satisfied, except one minor issue. With the A2DP and my Motorola HT820 headset, I get music, the call button / call functionality work fine, the volume works, the play / pause button works great. Where I'm stumped is the next track / previous track buttons don't work. I read one of the pre-reviews on "TheiPhoneBlog" that said everything worked great, though I didn't see any mention of whether they tested all of the functionality, or just the listening aspect. I've tried toggling the play button, just in case it was something on Apple's part, but still nothing. Anyone else successfully gotten this working, or is something possibly wrong with my phone / 3.0 build? I've had this same headset working with full functionality on a WM6 phone.... Any tips or suggestions, please let me know!
