use Voice Control without knowing PASSCODE

[etrain1971]

just press and hold the home button and you can dial any number.

It will not give you the contact/view photos as with the previous hack:
By hitting the Emergency Call button and then tapping ###, Call, and then quickly hitting Lock.

I believe it always has been like that (normal) since Voice Control came out so you can quickly access for a call or music...

There is a setting to disable that under passcode lock.
