Broken sleep/wake button iphone 4s?

Earlier this morning my sleep/wake button on my iphone stopped 'working', i don't mean it's not responding, but you just can't click it anymore. I'm pretty sure it's jammed in place too far down, as it's definitely not as 'raised' as it was originally. Either that or it's stiff/stuck and won't move.
it doesn't matter how hard i press on it, it doesn't move down as if i was to click it.
i really can't get used to using assistive touch.
i've had this iphone for over a year, so i don't think apple would do anything to help this. Is there anything else i could do? (to maybe get it un-jammed or something)

Added (1). also, i used that button completely normally. I didn't ever over-do it, or press down too hard. It just all of a sudden stopped working.

Well it is a iphone 4s it might be good if you updated to iphone5s, or you can just send the phone to apple

Why do you ever need to click it? I haven't shut my iphone off in a year.

Many use this hidden feature especially on the 5 as a work-a-round. A bypass.
Best luck.
