Enter DFU mode with broken power button?

The lock/power button on the phone is broken after it got wet. Phone was working fine for 2 weeks, now it's stuck on the Apple logo after resetting network settings. Can i enter DFU mode without a power button?

In more detail: I dried the phone in dessicant for some days , then it was working fine for 2 weeks or so , with the exception of the power button which was electronically stuck at the on position. (after booting up, the red power-off slider would appear as if the button was being pressed. I could tap Cancel and use the phone as normal, only the lock/power button would not do anything. )

Anyway the other day i decided to reset my network settings after trying out an app from the iTunes store that tweaks the packet size to supposedly increase 3G data speed. After the reset, the phone is stuck on the Apple logo. It stays there for a few minutes, then resets and gets stuck again, and so on until i turn it off by holding down the home button for a while.

Any chance of restoring the phone somehow? Is it the power button that is broken or could it be the motherboard?

Thanks !

Here's How to put iPhone in DFU mode:

1. Start with your phone unplugged from your computer.

2. Hold the Sleep/Wake switch until you get the red slider and turn the phone off.

3. Start iTunes on your computer.

4. Hold the Home button down and keep holding it down while you plug the phone into your computer. Continue to hold the button down until you get a "iPhone detected...". Follow the screen instructions to restore.

you dumb $@$@ THE POWER BUTTON DOES NOT WORK. HOW IS HE SUPPOSED TO HOLD THE POWER BUTTON IF IT DOESN’T WORK.

this will work with a broken power button ONLY on the off chance that you have the accessibility button thing already activated. Possibly also if you let the iphone die but that's unlikely to work.
