Belkin has been working hard and has finally come up with the new TuneCast Auto Live FM Transmitter. This device is specifically compatible with iPhone 3.0 and has the ability pull GPS data from the phone to figure out the nearest and clearest FM frequency to use which is based on geographical data and also on the recommendation of other local users. With the ClearScan Live application the iPhone interface can be controlled. This helps in reducing device juggling. It is will be available soon, early this fall in fact for $80.
