As far as I know we still able to download firmware through Nokia Care Suite. We won't be able to get the updates ahead of time without Navifirm but at least we still can recover or flash our devices if something happens to them using Nokia Care
Well.. that was inevitable really.. the moment they signed that contract with Microsoft it was pretty much game over for the "we can do whatever we want" behavior.scumbags carriers and Microsoft are responsible for this. So sad that Nokia is in such a weak position that they have to bend at the every whim of external forces.
