today I discovered something strange end disturbing. When I put my iPhone into my docking station it goes into some kind of "dock mode", which means it plays a lot of sounds (except calls or alarms) only through the 30-pin-dock-connector and not through the speakers (if I plug in headphones it of course plays all sounds through the headphones, but doesn't matter)
The annoying thing is, that when I pick the iphone up and it has been sleeping for longer than about 30 seconds, it doesn't recognize it's no longer in the dock. I have to put it into the dock again and then pull it out to make it recognize it.
This is pretty annoying.
Anyone else expierencing this? Is there a way to disable the "dock mode" (or whatever it may be called), I don't need it anyway ...
