Put the phone into DFU mode and restore it in iTunes.
With the phone powered off:
Press and hold Sleep and Home for 10 seconds
Release Sleep, continue holding home for 5 seconds
Release home
Phone should be completely blank, no logo or anything. The phone is on however.
You should've seen the apple logo briefly, then a flicker, then the apple logo again, then the screen should appear to have shut off. Plug into your computer, itunes / windows will recognize it as a phone in recovery mode.
Click the restore button in itunes, wait for it to complete.
