iPhone 4 Wont Turn on + Broken Lock Button = Frustrated

Hey everyone,

Quick question. I have a iPhone 4, and it randomly shut off (Had 90%+ on the battery). I cannot get it to turn back on. I have plugged it into 3 sources, including a computer with iTunes.

I have held down the home button for minutes, I have tried all that I can.

The popular answer, after researching, is hold down the lock button and the home button and plug in and it should work.

The catch is, my Lock button has been broken for about 4 months. (It doesnt work at all...ever)

Does anyone know of any other way to get the phone to turn back on?

Thanks for your help!
