If you are in India or a few other countries where the Ovi Store is still not available via the Download! client on your Nokia 5800 or the N97 (if you are lucky enough) then you can simply go ahead and install this installation file that I was able to pull from the Nokia N97.
I’ve tried installing it on a Nokia 5800 and it works perfectly. Nokia, you know what I am going to say. Why do this?
