Hey Jake welcome to WPCentral forums ! I am using windows phone 8.1 Developer Preview on Lumia 920 and yes I can wait for cyan firmware update hehe :wink:
It's an absolute beast. It was kinda hard to get used to the size difference coming from using a 920, but now I love it. Now I can browse the web using desktop mode and I don't have to zoom in to read!
Hello Jake and welcome the WPC comminity. I have a Lumia 920 and I am still holding out for the update. Looking forward to it Great hear you are enjoying the 1520! A part of me has been considering it.
