Possible next-gen iPhone surfaces on Vietnam sites

Another possible next-generation iPhone prototype has surfaced, this time in Vietnam.

US blogs reposted video of someone holding the phone and photos of it being taken apart. The original Vietnamese Web sites could not be accessed Wednesday afternoon.

The iPhone looks similar to one found in a Silicon Valley bar recently. That was sold to Gizmodo.com, a gadget blog, in April for $5,000 (£3,385).

Apple is notoriously secretive about unfinished products. It confirmed it owned the Gizmodo phone, but did not say it was the next iPhone. Analysts expect a new model in June.

After Gizmodo returned the phone, law enforcement searched the blogger's home and seized computers. A dispute over the legality of a search warrant is ongoing in California.
