From what I understand, Apple has incorporated GLONASS in each iPhone since the 4S... Does the external antenna make a big difference in terms of signal strength/speed?
That is what I'm hoping. User reports seem to show improved accuracy by 3X, faster satellite acquisition, more satellites tracked, better performance under partial cover, and more data points recorded than iPhone GPS alone.
