is there a CSI episode, where someone use the geotagging to frame someone for murder??
clone someone phone sim card, put in another phone, go and hit someone, take a picture nearby, and go off.
police will catch the person and hang him/her, while the hitman go away to Las Vegas for R&R.
The solution, NO internet access for phone. no twitter, no upload of photo. just use plain nokia phone which just make call.
