My iPhone has been frozen on a black screen for longer than 24 hours and it won't die?

My iphone 4 froze 2 days ago and its on a black screen and still hasn't died, When will it? It was on around 80% when it froze

When this happens do a force boot, hold down the power button and the home button until you see the apple logo, then let go of both. Do it now! The phone of heated up could have a hazard of exploding! Hurry! Never let a phone heat up too much.

  • My iphone 4s has been resetting for four hours? I wanted to reset my iphone because it was jailbroken but I didn't want it to be anymore.

How much longer should it take? Or should it even take this long? If I'm suppose to be waiting this long, how much longer should I wait? If not, what should I do?
