One thing I have grown to enjoy is to listen to podcasts on my pda phone. I found Ipodder was a great program to keep you up to date with your podcasts. Now they have changed their name to Juice.
If you want to find a way to fill your new 1Gb card on phone and pass your time listening to some podcasts give this software a try! Anyone with a Podcast favourite? Personally I enjoy listening to TWiT
