Apparently what this means is that the Iphone 4S should be able to look for almost twice as many satellites in the sky compared to the vast majority of GPS receivers. On top of that the GLONASS network reportedly works better at the extreme north and south latitudes, due to the orbit of the satellites.
I just thought this was pretty cool for bushwalkers! Down in gullies and under trees where GPS is a bit hard at times and this should help.
Apparently some Sony Ericsson phones and a couple of new Samsung Tabs/phones also supports it, as does the new Garmin eTrex lineup.
All you gear freaks with more than 6 month old GPS units bedda get out and replace them
