Indeed - since my old Symbian mobiles back in the day, it has always been the carriers who hold up firmware updates.
As I type this Sony have had a Lollipop 5.1 ROM out for my current Xperia handset for over two weeks. No sign of it on Vodafone UK anytime soon. Time for the networks to stop their crappy customisations and just do it all via apps.
