You could use AvantGo, iSilo, or Plucker, but from your phrasing, I'm guessing that you want to use the web page without having to reformat it for the handheld?
The only way to do that is to put it on an expansion card (a Memory Stick in your case) and then find a web browser that runs on the NX80v. I doubt Blazer or WebPro will work, since they are highly tied to Palm (and formerly handspring). Some CLIEs included NetFront, but I'm guessing that if yours did, you wouldn't be asking that question. Other than that, I guess you could search www.palmgear.com or a similar site.
