Anyway, due to this driving her nuts, I tested it with my phone and couldn't get it to work either.
So I made an appointment and took both phones to the Apple Genius Bar this weekend (I'd like to have taken the car, too, but driving through the Grumpyville Mall is frowned upon). There I waited patiently with other pissed-off iPhone users and listened to the soothing sound of Journey's Greatest Hits being played overhead.
The "Genius" there (who wasn't able to help, BTW, Tim) decided to make sure my phone's Bluetooth connection worked. So he said "do you have any music on this?" When I said "yes" he turned on my music app (which is set for random shuffle) and went to get a Bluetooth speaker. He set it down next to my phone, called up my Bluetooth menu, and looked over the list that appeared. Mumbling "I think the speaker is this one" he tapped a selection.
To his horror, he'd actually just linked my phone to the store's overhead speaker system. Suddenly Journey's "Any Way You Want It" stopped, to be replaced by a random selection from my iTunes...
Which was "The Internet is for Porn" from Avenue Q.
He hurriedly turned it off and muttered "It looks like your Bluetooth is working."
