So I woke up and had a out of the blue idea. So I've been docking my iPhone 4 @ home in my first generation iPhone home dock and it fits with no problem charges and does line out with no prompt screen. I know with ios4 with isimple you get a prompt screen. So I plugged my isimple into the back of the first gen iPhone home dock and dropped my iPhone4 in. No more prompt screen but because it does line out no volume threw the radio. So I'm thinking if I can disable the Line out maybe re-pin it that it would fix the isimple ios4 issues. I'll take pics and stuff later.
