well the 580 firmware has radio on it but it needs the headset which has the antenna inside to work, thats how it is with the 580 hardware.i really dont care much for the shake or fitness, im just a bit partial to the radio.

i guess there was some confusion in my post, to summarize, i am wondering if i can run the radio app on a s500 phone using w580 firmware if i use the 580 headset as an antenna.
