I'd love to be able to help you, but I barely understand this stuff myself...
Have just spent a few hours writing a very simple, condensed version of my website for mobile users. One thing I did come across was '
Cache-Control' and wondered if I should include this.
The mobile user friendly page is only 3.2KB, with no graphics. I used a mobile emulator like
this one to test it, then discovered
the opera mini demo. It was here I realised my normal web version wasn't too bad on a mobile device.
I do have a question for anyone who knows about this stuff:
I have a normal 'Contact Us' button on the mobile site, is this the normal way to have a mobile user send me an email, do they have an email client like outlook that would open or would they be left high and dry? (nowhere on my site is my email address visible, except in the source code).
Good luck with your situation.
