i have an iTouch that i listen to and have an iPhone that i read ebooks from. is there any bluetooth headset that will allow me to sync to both devices at the same time? that way i can still listen to my iTouch and still read on my iphone? i dont want to put my mp3's on my phone as i think, for me thats too much of a hassle and i did not get the iphone to use it as an mp3 player. just in case you're wondering.. thanks.
