That was kind of unofficial, but Cellpassion got a glimpse of it.

It seems that there aren’t many changes, only exterior ones, Nokia realised that the E90 needed a plastic surgery for better build quality. I’m not sure how "better" this edition is, but according to most sources, it’s worth to wait for this than buy the regular E90.

If you look to the E90 in the picture you will notice that it has a new colour, it seems bigger, and has no scratches on the display, unlike it’s counterpart on the right.
