Very useful as a replacement for native Latitude

I like that, unlike the native Latitude app, this works in intervals (I use 10 minutes) between which the GPS receiver appears to be powered off. Hence, Device Locator saves battery lifetime. I would love, though, if it automatically upgraded to the aggressive "cell tower switch" method when the phone is connected to a charger and if "cell tower switch" could be turned on and off directly on the phone. (Review lowered to 1*, because DL2 is available now.)
