Can I enter my pass code when in voice over mode? Is it possible to unlock the iPhone 4s when in voiceover mode?

I need to be able to enter my pass code in voiceover mode.
Slide to Unlock at the bottom of the screen.
Tap the first digit of your passcode once.  VoiceOver will read the digit aloud.  
Double-tap on that digit to enter the digit of the passcode.
Repeat steps 2 and 3 for the next three digits.
Your phone will now be unlocked.
