Maybe everyone knows this.. I'm using a free streaming radio app from my local NPR station and it works great - EXCEPT that when you click on the "Background" button so you can do other things on the phone, it backgrounds through Safari. Then, it doesn't seem like there's any way to ask Safari to do anything else. You can't open a second window and surf the web. Is this an inherent iPhone limitation or just the way these apps work? I thought the new 4.x os was to allow certain types of apps to truly run in the background. Does streaming audio not count - yet?
