I started to use Google Listen. It can search the podcast, even I found some Hong Kong Podcast too. Moreover, it can subscribe by using a URL of xml file. That is very good. I turned my Android phone to an "Internet Radio".
Android is great. The most of applications are free and are improving themselves. For example, yesterday, I got the latest of Task Manager 1.10.9. I got it has a battery indicator. I love it, it tells me the percentage of remaining battery!
