Wifi and GPS questions

[drjim]

I have a limited AT&T data plan, so I don't want to use my Internet connection through the plan too often. So a few questions.

1. If my wifi is on, does that override my AT&T data connection?

2. I installed Google Maps Mobile. It can find my location without GPS using My Location and cell towers. How can I turn my GPS off, so it doesn't transfer data?

Thanks.

Note that the GPS itself does not use the data connection, so it doesn't matter if Google Maps uses it or not. Google Maps is using the network (either WiFi or data) connection to get the map data, and would need it even if it doesn't use GPS for position.

If you were to buy 3rd party navigation software such as TomTom, CoPilot Live, etc., all the map data would be resident on your device and you wouldn't need a data connection unless you wanted to get traffic data.

Turn off gprs. Gps is an option in google maps. I do not need or have agps so this is not really an issue for me
