[QUOTE="Aptmunich, post: 1022800, member: 3850"] No , the 3G+Wifi model does have GPS, just like the iPhone 3G and 3GS have. To clarify: iPod: skyhook wifi location original iPhone: cell triangulation iPhone 3G, 3GS: assisted GPS iPad wifi: skyhook wifi location iPad 3G+wifi: assisted GPS Regular GPS systems take quite a long time to "lock on" to a satellite and this initial lock requires quite a lot of power. Assisted GPS uses cell triangulation to get a rough "guesstimate" of your position and then narrows it down using real GPS. This means it is just as accurate as traditional GPS devices, but is also much faster and uses less power. So in theory, if you're on wifi and enable GPS, you should be able to get GPS-accurate location results. [/QUOTE]
