Tunein radio is a nice radio application that allows you to listen to FM/AM radio from around the world. The app recently received an update to version 1.5. The application can be downloaded from either app world at this link or from their website directly at this link.
The application allows you to search by keywords, browse by location, or local radio using your BB location. It also includes talk radio, sports, and you can sort by language. If you like podcast you can search a wide range of podcast as well.
One of the reason why I like this app is because it allows you to listen to it even when you have poor cell reception.
