Yep. Apple really slays me with their refusal to fully implement the industry standard AVRCP protocol on the iPhone (come on Steve, INDUSTRY STANDARDS is what you quote for not supporting FLASH so get with it!). In any case, on my 3GS (and on Thursday iPhone 4!) I use a double tap of the main button on the F4 to start/stop music if it happens to drop out. Also, voice control works to start/stop and to skip tracks so it's not all bad. One thing I don't like is that streaming audio from Wunderadio doesn't mute correctly when a phone call comes in. The volume drops down but not enough. Perhaps that will get better once they re-compile with the new iOS 4 APIs for background audio. BTW - the new Pandora for iOS4 released today kicks but. Backgrounds correctly and mutes/restarts on phone call.
