My phone is Moto Q9c, Windows Mobile 6, with a Sprint SERO plan with unlimited data transfer.
Here are the 4 simple steps to listen to medical podcasts:
1. Download the Opera Mobile browser ($24). Internet Explorer should work fine but Opera is easier to use and has a better zoom feature.
2. Use Bloglines to subscribe to podcasts from your desktop/laptop.
3. Open Bloglines Mobile from your phone browser. Click on the "enclosure" link in the podcast feed. The podcast mp3 file will be downloaded.
