It's a Gingerbread feature. It should turn blue when you have a functioning Internet connection that can connect to Google servers. It will be white when you first connect, or if you are connected but it can't connect to Google servers, for example on one of those wifi connections where you need to open your web browser to do something before you can get on the Internet.
You can speed up the process of turning blue by opening Google Talk, which is the actual connection that it uses to measure it I believe.
