So, tracking all of those wireless access points becomes really important. So, Apple have now put the google locate in the iPhone.

Probably phones feed back cell is with gps coordinates and help improve overall quality of data.

Google claim that the My Location feature of Google Maps Mobile will get better over time and the only way to do this is to combine more detailed info against GPS. If they are capturing the cell id's then it is highly likely they will be capturing the 'relative signal strength indicator' or RSSI. This is basically a measure of how good the signal is, which correlates well (ignoring path issues) to how far you are from the tower. While they are there it would make sense to grab the ID's of neighboring towers as most devices will know this. You can also get the RSSI for WiFi which would also be worth grabbing. Cheers, Darren Hi John, All,
