But aren't you doing this AFTER you install the app? Which defies the purpose because by the time you turn it off, all your data is transferred.
Some OEMs include Facebook in their system image.
You could do it after you install the app but before you login/use it.
Anyone knows if the preinstalled FB application sends anything to FB even if you've never used it?
Theoretically it could, definitely. I don't know if anyone's done the packet sniffing for it.
If you are disabling the app in the Applications menu in Settings, the process for that app will not be able launch while disabled, so FB won't be able to collect anything.
