TuneIn is a radio app for BlackBerry and iOS. There’s a pro and free version with the main difference being that you can record radio with the pro version. With the app you can set up your favourite stations as presets or browse by category or region for your style of music or talk radio. The app may not work on the BIS apn (blackberry.net) so you may need a separate data allowance apart from your blackberry one to take advantage of it or failing that it fully supports wifi listening. The app is very good at compressing data to reduce the amount used. Particularly handy with many networks starting to offer mean data allowances with their plans.
