i was listening to music on my iphone through the built in speakers when i had a voice mail come in. i use a bluetooth head set from motorola (H700) for calls and voice mail and such. well i went to check my voice mail with the music still playing and the bluetooth headset still connected. when i click into the phone section and then on the voice mail tab the music started to play through the headset. i looked at the audio source tab in the voice mail section and i was set to my headset. as long as my iphone is in the voice mail section and the bluetooth headset is connected and selected as the primary audio souce i can listen to music via the headset. i use a pc not a mac. i found this out yesterday when i was driving before i did the new update to version 1.1.4 but it still seems to work even with the new update installed
