[TWiST]

So slap me if this has been covered but I am trying to update my facebook and because it was baked in I believe as a system app I am unable to upgrade it has any else seen this issue or know a work around, I know I read somewhere there was a program that allowed you to change the permissions of a certain dir so you could remove something preinstall and I am thinking that method may allow me to remove the old version and or upgrade it. Thanks!
