I'm looking at getting an iPhone 4 once it launches on Verizon next month. Currently I'm using a Blackberry Storm 2 and an Ipod Touch and will be happy to drop to one device. My question with the IP4 is with the Bluetooth. My car has bluetooth but only for calls. I currently have a LiquidAux Bluetooth connected to the Aux port to listen to music. Since I currently have 2 seperate devices I know there is no problems. What I'm curious about is with the IP4. Will I be able to connect it to both my car's bluetooth for calls and to the liquidaux for music. Also, if I happen to be playing music through the liquidaux and the phone rings would it switch over to the other bluetooth connection for the call? Any help is greatly appreciated, I definatly like my liquidaux as the car maker decided it was a good idea to put the aux port in the center console.
