I recently purchased a Foxl v2 Bluetooth speaker ( soundmatters.com). The IPhone 4 streams the music perfectly via bluetooth. I use Rhapsody, Pandora and the Ipod function. Range is around 25-35 feet, not necessarily line of sight. Rhapsody is currently using 64kps AAC+ and is rumored to be uprading music quality by this summer. The Foxl V2 is an amazing, quality product with very good bass, mid and highs from a very small footprint. Rechargeable battery with 4-8 hours depending on use.
