[Advice] How to get the original Apple Boot Logo back (aka i haven't read the sticky)

I've just jailbroken my iPod Touch using PwnageTool the other day and I've noticed that the original Apple boot Logo has been replaced by pineapple logo. It is not looking bad but I personaly prefer the Apple one instead.
Is there any suggestion about how to fix this?
Thank you in advance!

use the search button and read the pwnage tool part of the forum, there is a guide there

Thank you, I've got it fixed now. The original Apple logo is back!
