Rebooted a tethered jailbreak. Stuck at blank screen

[floridabear2]

My Iphone 4 rebooted by itself with the new redSn0w tethered jailbreak, it went to the apple logo and stayed on there for awhile i was not near my computer to reboot it with redSn0w and after a while the apple logo went away and left me with a blank screen that is lit up. It will not reboot with the hard reset and will not respond in anyway itunes does not show it and neither does redSn0w. PLZ HELP!!

Plug your phone into your computer. Push and hold the home and power buttons for about 10 seconds then release the power button and continue holding the home button.

Don't let it go until iTunes recognizes it.
