Why?
Please, re-visit this statement… (just today, the last phones got OS .107).
Beside that, Microsoft Mobile failed to explain this to me in the past, too—over the past twenty years! Obviously, this is one of the risks we end-users have to take, when going for a mobile phone from Nokia, now Microsoft Mobile. Microsoft Mobile does not leverage Microsoft Answers as feedback channel. Why ever. Therefore here, this question drowns in the Internet swarm. Instead, Microsoft Mobile wants us to return the phone (or change the Product Code ourselves).
@Armagon, by the way, do you know how OS updates are distributed – is that the Product Code too or something else?
