Opera Mobile (not Mini) for Symbian S60 with its d-pad bag of tricks was surprisingly usable with desktop websites, just crippled by a very low-res screen. Too bad it seems to have fallen off the face of the Earth even before Presto was abandoned.
I had some amazingly expensive Nokia 900 series phone that had WebKit on it for testing something for work (no way I was going to carry that monstrosity) and I remember it being impressive that it could actually faithfully render real pages. Still had garbage d-pad interaction.
