So I've had 4.0 since beta 1 and even after 4.0gm it still doesn't seem to work with the simple unit. It will give you a not compatible prompt, nothing new right? Wrong: you can't go past the prompt screen and if you use pandora though the simple like me it's a no go also. So I assume a simple firmware update is around the corner. Just giving you guys a heads up

 

Just finished testing with a USA spec and it seems to work fine with ios4
