Mobile output from Drupal 6

Hi guys,

can anyone advice on this issue. I have the first of a series of drupal sites successfully up and running.

My challenge now is to get the pages from my website outputing to handheld screens efficiently.
I looked around but I found nothing for Drupal 6 in terms of accessiblity modules.

I need help with either making an earlier module D6 compatible or finding a D6 mobile accessibility module.

Thanks for your help in advance.
