What about the 4G LTE Hotspot
I also read earlier that BMW is also developing a portable wifi hotspot that will use the space currently occupied by the cradle.
If that is true, I will just use the USB cable to connect the iphone 5 to the car and consider using the same "cradle space" for the yet-to-be-released wifi hotspot.
I echo some of the earlier comments that the timing (next June) is bad for the cradle as the iphone 5s or iphone 6 will only be a few months away. Who can say for certain if Apple is going to change the form factor then?
