I just put up a new site today for mobile devices using nothing but Drupal. The main feature of the site is a Google Custom Search Engine that I built to only search trusted (non-profit, government) health sites for health content. It also uses the pre-existing Google refinements for filtering.

So far the site is working great.

Here is what I used:

1. Mobile Theme

2. Google CSE

3. Google Analytics Module

4. Rss Feeds on health

It currently works well on my Symbian driven Nokia e62 and Nokia 770. I will test out Windows Mobile 6 tonight.

Future improvements I want to do do:

1. Build in a health "to-do" list
2. Build in the ability to have a phr on your phone

Here is the site, would love any feedback:
