I bring my experience, I have just buy an iPhone 3gs 32 gb to be connected to my 997 pcm.
To my regret, I immediately noticed that the bluetooth fortunately works but the cable interface to pcm the iphone not charging the phone while making them listen to mp3.
I feel really strange and not functional and also a contradiction.
What's more I can not understand if this is a problem of software or data cable supplied.
I do not know if it has already happened to some of you!
Ciao
thanks
