O2 Germany has decided to push the Lumia Cyan and Denim updates at the same time. The roll out will happen as a single update package to eligible Lumia smartphones by the end of the year.

This is bad news for Lumia owners using O2 Germany services since they'll have to wait a bit longer for their devices to jump to Windows Phone 8.1 (Cyan update). In the end, the carrier is saving itself the trouble of testing and launching two separate updates and has considered that combining them is for the better.

Interestingly, a Reddit user from Ireland notes that O2 Ireland has already rolled out the Lumia Cyan update to its customers. Guess O2 Germany is experiencing difficulties that aren't yet disclosed.

Anyway, the Lumia Denim update will come some neat features including launching Cortana from anywhere in the UI, new camera modes and 4K video recording at 24fps.

The Lumia Denim update will first launch on Lumia 930, Lumia 1520 and Lumia Icon by the end of Q4 this year. It will be expanded over the entire compatible Lumia range shortly after that.
