How about this: those of you with iPhones, Androids and the like, point
your phones at a page which reports $_SERVER['HTTP_USER_AGENT'] (like a
page which runs the phpinfo() function), and post what you get back from
that exercise and what device made the query. I'd like to see if there
is anything significant which indicates handheld platforms.

Logical, but I can save you that step :-) as I've been there done that..
Here is a PHP script (uses $_SESSION) for mobile users that I have found
to work fairly well. I'm absolutely sure that it contains false
positives, and potentially other minor bugs.. as it's just hard to keep
up with the ever changing UA's... but it's a start.
If it gets munged from email returns, I can zip it up.
