Should I have all 3 types enabled (Wireless networks, Satellite and aGPS)? I don't fully understand why I need one vs another, or if all need to be active or not. Will the battery/sleep issue exist if only one or a specific combination of the three types are active? Finally, what does the GPS toggle widget (stock moto one) control? Is this just for satellite, or all location features in the settings? Other than for convenience, what's the downside to leaving the GPS toggle off? Can I not use Where's My Droid, Google Maps, or any other location based apps? Unless I manually enable GPS? Where's My Droid is really the important one to me... I can turn GPS on for everything else, but if I lose my phone I'm outta luck. I don't plan on using the navigation app, so really the GPS would only be wanted to tag photos taken and for other location based apps, maps, etc. Thanks!
