Apparently this is the so called Nokia N97 Mini, an unannounced handset we can't really tell you much about. We just have these two photos, judging by which device appears to be slightly smaller and slimmer than the regular N97, and it's also has a few subtle design changes, particularly on the back, where the camera has lost its sliding cover.
That's all we can say for now. The device looks real, and we expect to get some additional details in the near future.
