As you know, there's more ways than one to stream music from your mobile device. The one we are discussing right now adds a little spice: you can preload music while online, and then listen to it even when there is not an Internet connection available.
The channel themselves work on low bandwidth connections, and as well as listening to music ranging far and wide you can access news and sports information on the fly.
For its part, supported devices include iPhones (of course) and Android phones like the T-Mobile G1. A recent update enables you to listen to FlyCast channels on your computer, using a player quite similar to the one featured in the phone version. Both Macs and PCs are supported so far.
If you think this solution is what you have been looking for in your pursuit of a better aural experience, you can always download the pertinent version from the iTunes Store and get started in no time at all. The service is constantly updated, too, so also make a point of checking the site to see how things evolve.
