One more working thing is that both my clickon FM transmitters do work again. The Belkin TuneFM works perfect again and a cheap chinese clone works partly, it only tunes up (unfortunatly that's the one with the best range and sound quality). On the older firmware both did not work. Seems that it has something to do with the software compatibility of the (speaker)dock system.
Since i use my iPod mainly stationary in the livingroom it would be nice to have a function that the backgroundlighting stays "on" while on external power AND turned "on". Now one can only time it or turn it "on". And when "on" it also stays "on" ALL the time, even when the iPod is turned "off"!
