Hi, I came across this on phonescoop.com. ACCESS built a web browser with pan/zoom functions sort of like iPhone's Safari or the upcoming Opera 9.5. The link to download it is here:

Looks like it has AJAX support but no plug-ins. Also there is a warning about the app being unstable if you install it to removeable storage.
I'm going to install this on my phone as soon as I'm out of work, if there are any problems, I'll post again....
