Is it really neccassary to disable the GPS signal when the Desire is not actually using GPS? Firstly i thought well I am not navigating so it would not be used - TRUE but actually it is being used for location services, especially for weather. So do we really need an on/off widget on one of our pages to turn it on/off? Personally i think not when it is in use there is a sat image in the top toolbar - therefore using it as expected when using it. Any reason why some people suggest turning it off?
