How to root Galaxy S with updated firmware?

[MobileVisuals]

My device has been upgraded with 2.3 Gingerbread. I try to root it and I follow the guide

http://samsunggalaxysforums.com/show...alaxy-S/page35

This does not work, I get "signature error". The "update.zip" in the guide is probably for the original firmware for Galaxy S(I9000).
Is there any way to root my Galaxy S now, since it has 2.3 Gingerbread instead of the original firmware?

Hey, Chainfire's method has always worked for me and my Galaxy S1 & S3.

XDA - Chainfire Root for the S1

Read the page carefully before flashing.

No worries, as I said for me it's worked every time without fail.
