I'm interested in hearing more about iPhone pairing. I currently have the old style SMH10 (non-USB) paired directly to my iPhone. I plan on adding the SR10 in order to add both the Garmin Montana and my Yaesu VX5 into the mix. I stream music from the iPhone (with the SMH10 able to control the basic iPod functions, I don't want to lose this), and very rarely use the phone feature (mostly for calling my wife to tell her I'm on my way home from work). I'd like to keep the iPhone paired to the SMH10 for music, then add the SR10 for everything else.
