As we can see in the photo above, BlackBerry Z3 will apparently come in a variety of colours for the Flip Casing.

We can remove the back cover (with some difficulties) and put this into place. However, whilst this is still a non-removable battery, we can get to catch a glimpse of it when we remove this back cover.
