Re: iPhone connectivity......
Be aware that the iPhone 5S will be shipping with iOS7...while theoretically that shouldn't matter, when evaluating comments from folks who have paired earlier models (iOS6 if kept current) it may not be the same as with the new release. There also will likely be no experience available with iOS7 unless someone was in the beta program.
(I'm also upgrading to the 5C at the end of the month, although I have the 730N)
