How much does WiFi help when you have it on both Wifi and still are connected to the mobile network? I have it on both when im around the house but i cant really tell how much it helps

According to what I have read, when you are connected to WiFi, data goes that route.

And your WiFi connection might be faster than your network connection.

Ditto to both the above. You should notice significantly faster page loads with the browser and faster file downloads.

I too understand the BlackBerry will use wifi in priority over the mobile network, but that is not a guarantee that some data will not be exchanged on the mobile network if it is enabled.
