hi all, Just bought my Nexus S 2 weeks ago and i wish to know more about it. 1. My Nexus S model number is I9023XXKD1, is this model the "Nexus S 4G" that is separated from this forum? 2. Do my Nexus S requires internet connection to use the GPS function? I heard from my friend that Nexus S has a "built-in GPS IC" which could directly detect my position from the satellite without internet connection, is it true? thanks in advance.
