My iphone is stuck in the lock screen?

Okay, my iphone is totally jacked up right now. First, earlier today my lock/power button stopped working completely. (I have an iphone 4s by the way) So to solve issue i turned on the "accessibility mode" so that i could lock my phone. But i was messing with it and somehow i got the "favorites" category of accessibility stuck in the lock screen. So i'm unable to swipe the screen to unlock my phone and i'm unable to hard reset it because my lock button doesn't work! I have no idea what to do. I'm afraid that if i hook it to my computer and restore it, (which seems like the only option) then i won't be able to turn the phone back on because my power button doesn't work! Also if i let it run out of battery then i won't be able to turn it back on. IF YOU HAVE ANY CREATIVE IDEAS Please ENLIGHTEN ME.

Try holding the home button (that circular button on the bottom of your phone) for 10-15 seconds.
WARNING: It will turn your phone off. My idea is that by restarting your phone it might fix your lock button.

I don't know if this is what you want to do but it's worth saying.

Try bring it to the Apple Store, going this far and doing it yourself can be very risky. It can cost you a lot of dollars, but at least you have a guarantee to fix your iphone. And that everything on your iphone could be saved and not deleted. (Photos, Videos etc.)
