The only way to downgrade for certain is to root your phone, but we're looking into a way to do it through more official means and avoid rooting.

And another thing :
One of the things I hated in ICS is the boot screen when I power on the Nexus S , can I change the contents of the folder from the stock 2.3.6 and copy them through Windows to the Stock rom of ICS and them install it ? same question is to stock Camera app , can replace the .apk from 2.3.6 folder in windows to 4.0.3 and install it ?
What you're describing is essentially the basics of creating a custom ROM. In order for the stock recovery to install an update, it has to be signed by the manufacturer (or Google in this case). Changing the contents of the update zip breaks the signature.
One thing you might be able to do without root is install the old 2.3 camera app. You'll need the CameraGoogle.apk from a GB ROM (link: CameraGoogle.apk
) and put it in your sd storage. Then in the developer settings on your phone, make sure "Allow Unknown Sources" is checked. Use a file explorer to find and install the CameraGoogle.apk. If it works, it'll overwrite the ICS camera with this one. No promises that it won't have weird issues, though.
