Hello, I am new to this forum and hope that I can little tid bits on the Iphone 4. Though I have been learning different things on this phone it seems to be lacking in one aspect, I am a motorcycle rider and have a Chatterbox xbi2. The problem I am having is that the bluetooth volume is low when using the ipod or pandora, receiving calls are fine but not use the apps I mentioned. I know other riders that are using other phones with the same headset and there volume is outstanding. Any info on this would be greatly appreciated.
