Ugh! Once again my iphone isn't working?

Okay. Last night i was using my phone it was working perfectly fine then i put it in my pocket for maybe a minute. And then i took it out and the screen was black i tried charging and plugging it in to itunes and its still not working. Could it be charger that isn't working? I mean my phone was charged i think. And when i call it it rings it doesn't go straight to voicemail thats how i know its dead. I tried to put it in DFU Mode the apple doesn't show up. Could my screen have went out? Ugh! WHAT DO I DO? I'm so done with Apple i'm about to say screw it TeamGalaxy here i come.

I had this problem once, if your iphone is jailbroken it is a deferent problem, so-what i did to fix it i backed up with itunes and restored it and the problem went away this worked on my jailbroken iphone 4s 16gb, i didn't understand if the problem was from jailbreak or else

Try picking up a new charger if you can, if that doesn't work and you really really can't afford or don't have time for a new phone, take it in to get repaired, it could just be overheating. In the future, pick up a Galaxy and you won't have this problem.
