I tried it and it works. Don't hold the sleep button, just press it. The screen seemed to freeze for a second but after that it was fine.
Update please, Apple!
At the passcode entry screen, select "Emergency Call." Input any number, hit "Send" and the phone's sleep button in quick, almost simultaneous, succession. You will now have full access to the Phone app, which includes Contacts, Call History, Voicemail, and the Dialer.
