When ever you what to make a wap site, do care for tags. Its really nasty to work in wap environment. Its so sensitive even a single character mistake will return parse error. So do check in the www.w3schools.com.
If you are working with dynamic site, then be careful with the `&` sign. Where ever it is, in url or in body text. It will kill your page and you will end up with a eagerness of ripping your hair :D. If you are importing your data from DB, do replace all `&` with `&` at the end. There are other exceptions as well but `&` is the cause of most choked pages.
