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.

Next, it appears this unit actually has been turned on:

It appears to say "Inferno" on the screen with some text on the bottom that indicates the battery life is at 24%. It's hard to say for sure, but it could represent some sort of firmware diagnostics that we have previously seen on prototype iPhone hardware. This one appears to be called "Bonfire!".

There are also no screws on the bottom of this unit:
