Hi there thank you.
I read some comments in a couple engadget-like news-sites and some people have stated that their iphones have worked in other 'ipod' docks even without the dock stating its support, and speculated that it will also be the case with this device.
...but if Onkyo states support for the iphone on their UP-A1, made for their X07 line of receivers, why not say it on this media center? I guess the big perk of getting one of the newest Onkyo receivers is the universal port, which the UP-A1 connects to, and seems to provide around the same SQ as a digital coax or optical cable.
