I don't really know much about the SID softmod, but I do know that it would be a better idea if you tell your friend to use Krayzie Ndure Installer v1.1 because if your friend runs into any problems with softmodding he would have a bigger support base here. Not saying that SID is a bad installer, I'm just suggesting your friend use Krayzie's because it's more user friendly and pretty much dummy proof.
To get this softmod you would need to go to xbins. Here's a tutorial
on how to access this site. Oh, and yes, make sure it's the PAL version of the softmod.
Hope this helps.
