Power it down by holding BOTH the power and home buttons down at the same time until the screen goes off.

Then, Restore the phone to "factory" using Itunes - to do this you will have to place it in DFU mode again.

After the restore is complete, DO NOT SYNC ANYTHING TO YOUR PHONE.

Then re-pwn it. Should work great.

There has been an issue with installed apps creating that problem, but can be fixed if you pwn the phone after a clean restore.
