Actually I want to do the same thing on my Nokia 6230 and am getting nowhere. Three problems:
1. Do I use a WML file or a WMLC file?
2. Where do I put it? All the public folders do not recognise a file with either extension.
3. The browser does not seem to like file://gallery/xxx.wml
I could do it so easily with my Siemens SL45i but with the Nokia it seems to be a big issue!
The way to transfer xml to wml called xsl. This is also a kind of xml file. There are tools that can apply that stylesheet on the fly, this is that all portal do nowdays.
