LG Xenon compatibility issue

[KD5NRH]

In addition to the ongoing Linux issues, now my new phone is having trouble with SmugMug. Of course, the regular site isn't set up for tiny screens, but the /iphone site worked fine with my Nokia 6126. When I go to it on the LG, I can see the menu listing, but when I try to click on Galleries, Categories, or anything else, nothing happens. The phone acknowledges the click, but doesn't go anywhere.

For the record, it's an LG Xenon, with AT&T service, using the default browser.
