My iPhone 4 won't turn on - 3

So I've had my phone since September. It's always worked fine, such a good phone, haha anyway. I was up til like 5 tweetin' & on Facebook & what not, then put it on the charger & fell asleep. I woke up like 20 minutes ago to my phone not turning on… It's just a black screen, I tried different chargers, it's not dead. Also my lock button is like jammed in, and down so I can't use that, but any chance does anyone know what to do or how to fix that? Well please help because I need my phone & I don't know what to do… Thank you all.

You have it upside down…

IPhones are only good to use as a paper weight… Why don't you buy a real phone?
