you have a misunderstanding !!
The software isn't stupid at all , it's totally correct
Updates are available for certain phones bought from certain locations .
For example , a phone bought from Dubai can get an update , but another bought from Europe can not get an update.
Wait till Nokia makes an update for your phone , however you may not get one , but this is unlikely for new phones , you might face this case after multiple updates .
That's why when you check for updates thru Nokia official web site , they ask you to inter your phone's IMEI number , not simpley the phone model ! make sense right ?
