My iphone 5 is frozen and i can't do anything?

Added (1). I was just on my phone as usual and i was on this app called pump up and it was loading something and all the sudden my phone froze and it won't turn off, whenever i plug it into a charger it doesn't say its charging. And if i hold down the home button i can hear siri but nothing shows up. I also can hear texts coming through and my ringtone when someone calls but its still stuck on the same screen! What do i do?

Added (2). i also can't hold down the sleep/wake button on the top right because it is jammed

When the iPhone crashes, locks up in a way that prevents it from being turned off, or just isn't working as it should (you'd be surprised at how many problems or strange behaviors can be solved by a simple reset) you need to reset the iPhone. Here's how:

Begin by holding the sleep/wake button at the top right of the device and the Home button at the bottom center of the face at the same time.
Hold them both until you see the screen go black. In some cases, you may need to keep holding them even after the red power-off slider appears. If it appears, just keep holding it.
Wait until the silver Apple logo appears.
When this happens, you can let go - the iPhone is rebooting
