how do i block my caller id on my samsung galaxy s2

How to hide my phone number
Samsung has changed the settings in Galaxy S2 so it is no more possible to simply say:
[Settings] > [Call settings] > [All calls] > [Show my number] > [Hide]
This option does no longer exist that simple. Has anyone found out where Samsung has hidden this functionality so I can choose to hide
my phone number. ?

Settings > Call > Additional Settings > Caller ID

Alternatively, there is an app for that:it is called Hide Caller ID (click the link)
