"That is interesting because I have both Facebook and the Data Manager disabled on my Android phone. I am not sure if that actually helps but I am able to disable both."
Yeah, I think the difference is on your phone, they shoveled^H^H^H^H pre-installed these as apps. On the phones where this can't be disabled, they improperly stuck these on as SYSTEM apps. Since system apps are supposed to be performing important system functions, the GUI doesn't allow disabling them (most people wouldn't want to disable for instance the phone dialer or settings menu.)
