Written and produced by the writers and producers of the Kevin Smith cult classics (Clerks, Chasing Amy, Dogma, etc.) This is my entertainent cast, I don't learn much off of this one, but it keeps me laughing and interested (WARNING: Mature Content)

This cast is a forum related to all things mobile. Subject matter is often related to WM Smartphones; however, they do talk about other platforms, as well as other devices such as PSP, iPod, and GPS units.
There are a ton of others that I lisen to as well, but these are my favorites.
