My DS7550 has stopped working with my iPad2 and my iPod Touch after upgrading to the new OS.

Charges very slowly...shows " no volume available " when adjusting volume control on iPad or iPod.

Purchased dock less than 2 months ago, and while I believe this is an Apple problem, Philips should address the problem on this board.

Google search shows many problems with 3rd party docks after Apples lastest OS updates.
