Is There a Simple Way to Restore?

[Ringo4422]

I apparently bought a defective iPhone. The battery was fully discharged when I got it. I had to charge it for 15 minutes before it would even turn on.
Anyway, I jailbroke it, prepared it for unlocking when I realized that it won't turn off with just the power button. I have to press Home and power together to turn it off. I guess this explains why the battery was completely dead when I got it.

The BIG question here is how would I restore it to make it look like I didn't mess with it? I want to exchange it for another one but it is Jailbroken. Could someone give me some insight?

You have to use the revirginizer. That'll take care of it. Post a question about where to get it and how to use it because I haven't got any experience with it...
