Can I disable geotagging and delete prior geotag information in photos?
I found a camera mod here that allows disable of geotagging and does it by default.  It looks like I either need ADB or root to install it.  

Edit:  The camera mod doesn't work, as far as disabling geotagging.  

Updated Answer:  The Amazon App Store has Camera Advance Lite (and a non-lite for that matter) that has the option to turn off geotagging, which is disabled by default.  

This app Geo Eraser looks like it will remove prior geotagging info.  

It appears that using a Gingerbread based OS will fix the problem as well, based on my conversations with Gingerbread users.
