Reset Iphone after Jailbreak

[thaism2]

I am selling my iphone so I jail-broke it through jailbreakme.com.
Then I realized I still had all my information on the phone, so I reset it.
Now my Iphone is stuck on the same screen, which is the opening screen with the apple logo. It won't turn on or off. What do I do now? Is there a way to fix this?

Try hooking it up to iTunes and restore from new.

I wonder what a certain poster espousing the "erase all" has to offer here?
