I'm using a iPhone 4s with the new firmware 5.1.1 with my x930bt. Never had this problem until after updating the phone. The physical buttons on the x930bt that should skip forward or backwards are not working when using the ipod feature. Doesn't matter if I'm using bluetooth or the physical cable. The buttons do work when using Pandora or iHeart radio...or any other music app, just not the iPod. When I press the the forward skip button when using the ipod feature, the cover art for that song flashes as if it is the next songs cover art loading, but it isn't. And it never skips to the next song.
Pleas let me know if this is happening to anyone else. Very frustrating problem to have.
