Hi Andy,
Thanks for the insight. This is a slightly different issue in terms of the cause of the problem and you may have hit on the solution. If you would be willing (since it was not the problem I had, I can't start it), would you please start one.
If at a loss for the title, maybe "iOS unable to connect two devices at once" or "Cannot connect two iOS devices at the same time". You well may be able to come up with a better one.
That way others could join in and could be referred to the Apple Feedback sight to report a bug at
http://www.apple.com/feedback/iphone.html to choose Select Feedback Type: Bug Report then fill out the form. With a number of people reading the topic and posting, then submitting feedback, Apple might see a problem, then fix it if they can duplicate it.
