Hello, friend! Thank you for your article. I really thought that everyone forgot about Nokia so it is pleasant to know that it is not true. I am also interested in nokia phones, especially old ones. We have done this with my friend and even created a channel and made videos with our adventures. I even tried to fix and replace some details with the help of internet. I have seen some useful info on those sites so maybe they would be useful for you also
