Fitch is not an unknown rating agency. It is one of the big 3, along with Moody's and S&P. Typically when one downgrades, the other two start looking more closely at the company as well and in many cases end up downgrading the credit rating. So it is a reasonably big deal for Nokia as it just means that their costs have just increased, which is especially going to hurt given the low margin business model Nokia seems to be running. Makes it even more important for them to get their top end phone strategy right.
