touchscreen problem

first off, my on/off button broke a month after i got my 4S, a day after i had a dream it broke. funny.

now, 8 months later, my touch screen decided to not work.

i have had the accessibility button on and it is the only thing that can move on the screen.

i cant swipe to unlock.

siri is the only way ive been texting but its a piece of garbage.

tried to restore it from my computer through itunes, but the phone has to be off. 😢

any idea what i should do other than parade through each apple store in the try to fix this.
