To turn off Geo-tagging for your photos on your cellphone camera here is a link that shows you how. http://icanstalku.com/how.php#disable
I checked the setting on my phone and this was already turned off. There was a segment on the news the other day telling how people can track your photos. For example you post a pic of your new flat screen tv, which has your home address associated with it, next you post a pic at a restaurant...if someone is watching they can determine you are not home and this would be a good time rob you.
