Wheres M77, it appears the emrgency pizza ordering option is back on the iPhone.

clicky

The procedure i saw was..

1. Lock device.
2. Slide to unlock.
3. Tap emergency call.
4. Hold sleep button until the power down prompt shows. Click cancel (you will notice the status bar turn blue). Type in 911 or your emergency number, click call, and then cancel it ASAP so the call doesn’t go through.
5. Lock your device with the sleep button and then turn it on using the home button.
6. Slide to unlock, and then hold the sleep button, and in 3 seconds tap emergency call. This will spazz out the phone and cause it to open.

The version I saw said you had to keep the sleep button held down (i.e. the phone would re-lock when you let go) but the video you posted doesn't seem to require that - may be down to a slight difference in firmware versions.

I just wonder how on earth someone came across it. I mean, it's not as if you'd ever do that sequence of things by accident.

Ther must be some really really obessive people out there trying all sorts of combinations.

Don't look at me. Too many combinations for me to remember. So this is a new feature. Now where is that emergency pizza button?
