I have been trying to find the same thing! So far, the only thing I can come up with is going to settings> location and security> and unchecking "use wireless networks" and "use GPS satellites" . After doing this it seems toggling the GPS on and off in the notification bar works too. I wish there was a way to just set the camera not to geotag the photos, just in case GPS doesn't get turned off after mapping or something... Maybe there's an app out there for that!!
Can someone help me out?
