My iPhone just hanged and never turned on. It only shows black screen with an apple logo and the icon of reading, shutting down. What will I do?

What were you trying to do when it happened?

Was it hacked/jailbroken?

Have you tried simultaeously pressing and holding down the sleep and home buttons?

Have you tried connecting it to your computer (iTunes)?

Failing that you could wait for the battery to run down and see if it restarts after being put on charge...

Same deal here. The phone doesn't actually shut down 100%:

If I'm on a phone call it does not drop the call, but I can't hear the person and they can hear me for about 15 seconds until the phone finishes it's 1/2 reboot.

I exchanged my phone for a new one (sure it was refurbished) and still the same problem.

Restoring as new isn't doing the trick.

ios7 strikes, again, me thinks.

Read this article on putting your device into recovery mode prior to attempting to restore the device.
