Here's a link to the FIA's detailed statement. It is very long, but very interesting and includes some snippets of emails between the drivers and mechanics concerning Ferrari setup. I also find it interesting that Hamilton responded with no info for the FIA. My guess is he's lying and is simply playing the company line, which I suppose could be considered very loyal. However, the FIA made it very clear to the drivers that if it was found out later that they had withheld any info, the penalties would be huge. For his sake, I hope he really knew nothing about any of this, but I find that hard to believe.
