ip

Hey all!

So, we're looking to develop a mobile website. On this mobile website, we'd like to automatically populate a user's location (with proper fallback) based on their IP address. I'm aware of geocoding a location based on IP address (mapping to latitude, longitude and then getting the location with that information).

However, I'm curious how accurate this information is? Are mobile devices assigned IP's when they utilize 3G, EDGE, and GPRS connections? I think so. If that is so, does it map to a relatively accurate location? It doesn't have to be spot on, but relatively accurate would be nice.

Thanks! -Steve
