Maybe this is not news. But today while seaching for some FAQs I noticed that there are FAQ pages in Nseries.com and also in Nokia.com and they are not the same.
If you search the same word for the same devices you'll get totally different FAQs in the two sites.
So, head over there and check it out. Which one is better, I don't know, but the fact that it's different is something.
So make sure you search the support pages in both sites as you may find the answers on one of them.
