If this is even possible, I'll be very shocked. I don't know for sure
one way oe the other, but it would be extremely interesting if mobile
phone web browsers implement the technologies needed for AJAX.

And what might those "technologies needed for AJAX" be?

JavaScript, and some kind of means of communicating between JavaScript
and the server. For the latter, the non-standard XmlHttpRequest is
normal, but in a pinch, a zero-size frame and decent DOM support will do
(assuming you want to ignore the 'X' in the rather poorly named "AJAX"
acronym, as most people do... otherwise, an XML parser will be needed
and XmlHttpRequest is the only reasonable game in town).

Oh, is that all? Every decent browser (Opera for example) already has that. For
quite some time now, in fact. And - surprise, surprise! - it runs on your
average mobile device like magic.

I was unaware that Opera had a browser for mobile phones. Nevertheless,

http://www.opera.com/products/mobile.../faq/index.dml

See the next to last question. That makes me rather skeptical about the
ability to use JavaScript for AJAX tasks. It's too vague to reach any
specific conclusions.

Now you are. In fact, they're so sure their browser will rule the world of
mobile devices, they gave away their (ordinary) web version for free.

Try it out (incl. the Opera Mobile TM). That should be enough for those conclusions.

That is perhaps good advice for someone who really needs to accomplish
this. I'm not that person.

Opera is *the* browser for mobile phones.

OperaMini is not their full mobile browser, that's for more limited
devices. OperaMobile is what you should be looking at.

Here's the supported standards for Symbian Series 60 devices:

Really, 'cause my mobile phone comes with its own browser that's not
Opera. As far as I'm aware, Opera is not *the* browser for anything,
unless you work in Opera's marketing department.

No, OperaMobile is what I hypothetically should have looked at if Jeff
had said that he wanted to develop AJAX applications that only run on a
few specific devices for which Opera Mobile is available. I have two
different J2ME-capable phones, for example... one implementing MIDP 1.0,
and another implementing MIDP 2.0... and yet neither could run that
application. AJAX applications that require Opera Mobile may as well be
written in J2ME client apps; unless they deal with HTML in the problem
domain as well, it will be much easier and probably more widely
compatible.

Nothing there about XmlHttpRequest. I know it's available on Opera's
desktop browser (though the implementation is rather quirky). Of
course, since it's not a standard, it wouldn't make sense for it to be
on that page. Still, I don't know how to find out whether it's
available or not. I'm sure not gonna buy a US $300 to $400 phone to
find out.

(I also didn't realize how limited and bizarre Opera Mini really is.
I'm now confident in asserting that AJAX definitely doesn't work there,
since JavaScript doesn't even make it to the client.)
