iPhone 3G turn off w/o button when it's been locked

[hidwoh]

So I updated my iPhone 3g to the 4.0 software with the intention of jailbreaking it. Unfortunately, my top button is broken and one has to turn off the device before they can finish the unlocking process. Does anyone know a way I can turn off my iPhone? Oh by the way, it's on the locked/ emergency calls only screen.

Thanks,
Oliver

Not without fixing the top button.
