Mt Whitney Zone Forums General Discussion Gmap4 = View topos/aerials *offline* and your geolocation

@Steve C

1. Thanks for the fix

2. Here is something I read online:
"Yes, the iPhone 3G and 3GS have a GPS receiver built-in. The original iPhone does not."

Also, I know that starting with the iPhone 4s, there is a better GPS chip in the iPhone. It is better since it can also see the Russian satellites (GLONASS). More sats = more data = better accuracy. But!!!, your phone can only use the Russian data if your phone has a current almanac for the Russian sats. For details see the pdf file on the Gmap4 Help page.
