It seems that Apple is having a hard time keeping track of prototypes of its 4th generation iPhone handsets, as another one ends up in the hands of someone who shouldn't have it.
The new photos appear on Vietnamese website Taoviet.vn. Rumors are that this handset was bought in the US by a Vietnamese businessman, along with an iPad.
We have lots of photos. On the whole the handset is similar to that acquired by Gizmodo, although one difference is that this one is marked as a 16GB model and seems to boot into a diagnostic screen.
Apple branded processor on display here.
Seems genuine enough.
