Help: Stuck at Apple Logo then Black/Blank Screen

So after some jailbreak fun and doings something wrong, I found myself stuck at a black screen just after the iPhone start-up logo.  I attempted to force the iPhone to restart many times with the same results until following the next few steps to restore my iPhone to factory defaults.

  1. I needed to turn off my iPhone by holding the sleep + home buttons together until the iPhone powered off.
  2. Using the iPhone (ipod) usb cable hooked up to a computer running iTunes.. Press and hold the home button without letting go, and plug your usb cable into the computer.
  3. Next the iTunes logo with the usb cord will show on the iPhone screen and the restore process begins
