"We're not sure why Apple is having such a hard time holding on to these next generation iPhones, but a Vietnamese forum Taoviet.vn has posted more photos (cached) of the previously leaked 4th generation iPhone. They've posted a large gallery of shots making it clear that they have a unit in their possession. There seems to be little new information posted, though the individual who submitted the link to us stated a Vietnamese businessman had bought it in the U.S. together with an iPad.
There are a few interesting aspects to these images that were not seen in the original leak. The case design is identical, but notably, the back shows that this is a 16GB model. The previous leak showed "XXGB" written on the back."
