I want to buy used Nokia N810. In my country, this nokia was not selled officialy. I have little choice. I find one annoucement, but this nokia has Symbian installed. So I ask, if it is possible to install OS 20080 on Nokia N810 which had allready installed symbian. And if it is possible, how i can do this. Can i use flasher ? Thank you for answer. Sorry for my English, I am from Slovakia.(EU).
