Apple.pro points [Google translation] to several images posted to Chinese microblogging site Sina Weibo showing what is claimed to be the rear shell of the "iPad mini". We certainly can not speak definitively to the authenticity of the images, and anything posted randomly to a microblogging site is clearly suspect until additional supporting evidence is discovered, but we have elected to share these images on our blog page for interest and discussion.
Notably, the rear shell does not contain a hole for a rear camera. Cases for the rumored device have been showing a rear camera, although those too must be taken with a grain of salt until additional parts evidence surfaces.
The user who posted the images has no track record of previous posts on the service, and thus there is no history by which to judge the accuracy of the claimed photos, and they are presumed to be fakes. Consequently, we are simply presenting them for documentation and discussion.
