TRY THIS!! Alright so for anyone that this DIDN'T WORK: I had this same problem, but it wasn't that big of a deal until my phone DIED. Without a power button, there was no way to turn my phone on. Well after charging my phone until it had a full battery, I then took my charger cord and plugged it into my laptop... tada! It booted right up, and has done that a couple times since, so all in all it's an easy fix getting it back on, even without the power button functioning at all. Hope this helps some of the rest of you!
