Most of the great apps and features we saw upon the introduction of Nokia's Lumia 1520
phablets, are going to arrive for other Windows Phone 8 Lumias as well in early 2014, along with Microsoft;s GD3 update, said Nokia:
This will happen later on, it won’t happen immediately. Some of the key updates for Windows Phone are in GDR3, so the notifications, some of the underpinnings behind it will come through across all devices and be combined together with the Black update.
And we’ll have stuff like Nokia Camera, Storyteller, the lock-screen will be integrated as well – it will be even richer, so you’ll have messaging, email, you’ll have notifications – so we’re really looking at how do we reward our existing consumers.
