I used to use AvantGo with the Palm. You could put any website on it's list. I would love for a maemo port for that.

It is available through the Garnet VM... kinda. Garnet has it's own requirements, I think you need an existing PDA and sync software (no doubt there is a way around that). Then my palm's only version was palmos3(?), the latest garnet uses a more recent version. AvantGo isn't compatable with the new version... There is a new AvantGo for the more recent os, but I can't install it since it dosen't recognize the new os. I just got it to work (it would update using the wifi just fine), before I upgraded garnet.

This thread has some options, but looks like they require a bit more work than AvantGo did.
