iPod touch How does Find My iPod work?

[talino]

Hello,

I've just enabled the "Find My iPod" option in the iCloud Settings page.

The iCloud web service has pinpointed my location twice, using two different Wi-Fi networks, to within a meter or two.

The device has neither a GPS unit nor a 3G connection. How can this process be so precise, assuming Apple doesn't have access to every ISP's database of IP addresses & clients' physical addresses?

Thanks.

@chown33: Does this mean that if I physically move a wifi access point to another location, "Find My iPod" would display the older address until someone from Skyhook drives by again?
