Yes
I just traded in my 2006 today. Had it from new and have connected all past 5 years of iPhone models. includind the 4 and also the new iPhone 4S. Make sure you are in your iPhone's Bluetooth settings page and that Bluetooth is turned on. You should see the message on your phone "Now Discoverable" before you attempt to pair it to the QX. I think the password is 1234 or 0000, check the manual. You can definately pair an iPhone.
I picked up a very nice 2010 QX today and was bummed that I cannot download my iPhone's address book to the QX. I get "FAILED" on the screen. Does anyone know if this can be done?
