Hey build issues did you have with the first two devices ??
I'm also still waiting for the last firmware 11500 update, and the four devices i sold today didn't get the 11500 update either when i updated them in the shop.
The first one I got was not properly seated in the casing on the right side of the screen, so when using the phone it had an annoying click sound when using the touchscreen.
The second one had a scratch on the inside of the screen.
And this third one has bad battery. Now the release of the firmware update is going to be during next week according to a Danish Nokia technician.
