Samsung Vibrant (Galaxy S)
Does anyone know if the Vibrant had different variations released???
If you feel brave enough, watch some of the videos on how to take the back off of the phone to see if there is a front facing camera and if so, which one it is. It could be the GT-I9000 or the GalaxyS 4G camera.
There are many ROMs now that support front facing cameras, but most have slight banding in low light conditions. Search for FFC mods at XDA Developers for more info.
