Another iPhone HD/iPhone 4G prototype has shown up on the internet and has been posed, torn-down, and shown off on video. This Taoviet prototype is similar to the Gizmodo prototype seen earlier in most respects, but is clearly labeled when it comes to storage -- 16GB -- and lacks the two screws on the bottom seen on the previous prototype as well as current iPhone 3G and iPhone 3GS models.
Reportedly a Vietnamese businessman bought the 4th gen iPhone in the US for $4000 but how Apple lost control of it remains unknown. The screen looks stuck on a firmware test reading Inferno and calling itself Bonfire!, so no bootable iPhone OS 4 or special feature hints yet (sorry iChat video fans).
Unlike Gizmodo, Taoviet tore their prototype down to the system-on-chip (SoC) and the chipset looks to be an Apple A4 similar to the blazingly fast 1GHz ARM Cortex A8 and PowerVR SGX chip found in the iPad. (We're still holding some hope for a multicore Cortex A9, but we're never satisfied).
More pictures and video after the break!
UPDATE: iFixit sent us word that, based on analyzing the part numbers, it looks like this A4 chipset has the same amount of RAM as the iPad. 256MB. Drat.
