So after getting tired of getting the prompt for the data connection every time I wanted to take a picture (geotagging enabled), I set the connection to automatically-connect in the Settings.
What got me was that the 3G connection was being made automatically with no indication of why. No way of knowing what was causing it. Application-update, desktop widgets? Having this On is simply bad news for the battery.
I am going back to selecting the frigging connection everytime I slide out the lens cover.
