I bought a new Ipad Mini 4 WIFI 128GB. I ran the Antutu performance test and was pleasantly surprised. It listed both GPS chips! I wondered if this was somehow wrong, so I took the Ipad Mini 4 Wifi with me in the car. Using a cached Google Maps, it accurately showed my position. Interesting. I am wondering if the Ipad Mini 4 128gb has been upgraded or they are using the cellular board in the current version?
