Yes, a cache problem would be what makes it work fine most times, with lag other times from using less satellites than it should be able to, and other times, not at all, until you turn it on and off. I am seeing all of that.
What I was getting at with the question of both was not whether it has aGPS, phones don't just included it, they really need it. But whether it also has functioning regular autonomous GPS.
GTen has had it work outside the US. In my son's experiment on mine it did not seem to.
GTen: Thank you. That is no use of wifi and no CDMA signal from any carrier, right?
As another test I put my phone outside, in a plastic bag, overnight. I had turned on airplane mode, the dialer code change recommended, restarted, and it with a GPS testing program from market. NO location this morning. I suppose that airplane mode is an imperfect test, and a false negative or false positive for autonomy is possible from it, but it does make me still uncertain the Epic has functional autonomy in GPS.
