Does it make a difference if I have Cyan or Denim installed before updating to Win 10 , Lumia 1020 ?
Just realised I could have updated to Denim before Win 10
the only difference I could see is if you were able to install denim firmware, you would then be able to install lumia camera beta which requires denim firmware to work.
I just got Denim it's more than a name change and allows for different apps to be installed, should be interesting to go win 10 afterwards and see what happens
