I'm using Nokia Lumia 620, India, No Sim. Nokia says that update is available. But my phone is showing that it's up to date.
Even if the update status for your device is 'Available', not everyone gets the update at once. So, you have a few options...
- Wait a couple more weeks by which time the update should appear.
- Find your local Nokia Service Center (Care Point) and have it updated there.
- Skip the queue and update your device manually using Nokia Software Updater for Retail - but this will wipe your device!
I won't link to Nokia Software Updater for Retail, but it's easy enough to find using your favourite search engine.
