Well I picked up my iPhone5 yesterday from the apple store (took less than 1 hr to wait in line and buy it

)
I have the RNS510 and the iphone5 is powered by the USB adapter using the USB-Thunderbolt cable and stream music via Bluetooth.
Also I was surprised that Siri worked when I press the button on the iPhone, it make the connection like a phone call and work for all things :-)
Anyway, as soon as the adapter is out I will purchase a retest, but I already know its not gonna work.
