Endless Paradigm

EDIT: I ENDED UP DOWNGRADING TO AN UNTETHERED JAILBREAK SO I DON'T NEED TO WORRY ABOUT DFU

Yesterday When I got home I put my iPhone on the Charger for about a half hour
When I came back, the sleep button seemed harder to press than usual
Now Its Completely Stuck and won't work
I don't have the money to replace the phone or get it repaired
The main reason this is a problem is because my Phone has a Tethered Jailbreak and Every few weeks something happens and I have to boot tethered again but now since the button won't work, I won't be able to get into DFU Mode to boot it
I am currently using Activator to re map the sleep button so i can lock my phone
This is my main Phone and I don't want to risk repairing it myself unless its a simple fix (like replacing the back glass)
Can somebody tell my how to fix this (Possibly Without opening it)
or a way to boot DFU without the button?

You can boot into DFU directly from redsn0w now.

I actually ended up downgrading to 5.1.1 untethered with the sn0wbreeze ipsw

still, thanks for the help cause i had to get into dfu to downgrade it!
