There is already lot of confusion about Apple next generation iPhone. What it will be called iPhone 4S or iPhone 5? Will there be two separate new models or just one new model? Will it have bigger screen, A5 processor and so on? And today Engadget posted pics of iPhone N94 prototype front assembly, which has added more confusion. The part looks every similar to iPhone 4 front assembly with just one difference it has a dotted pattern near top that looks like webcam LED on Mac computer. It is very likely that N94 prototype is the cheaper 8GB iPhone 4 and hence the components are very similar. Engadget explains:

That said, do bear in mind that according to the mark along the bottom of this part, we're apparently looking at an "EVT1" (Engineering Verification Test) piece from March 3rd 2011 (making it about three months older than the white N94 back covers that made the rounds last week, assuming they're legit). Additionally, when our sources last checked around June and July, the N94 had yet to hit the DVT stage, so it's hard to determine whether these parts will remain the same in the final design, or whether the N94 will even make it to the production line at all.

On the other hand, our sources pointed out that an elusive N97 device -- previously reported by the Wall Street Journal as a tiny iPhone -- had already reached "DVT" (Design Verification Test) stage back in June, though there's little information about it other than that it's been tested with various cellular technologies (though plagued by some bugs related to switching between specific frequencies back then), plus it may sport a camera module supplied by Sony, which was semi-confirmed by Howard Stringer himself back in April. Whatever the N97 ends up being, hopefully we'll have something at least as slim as our little souvenir from Beijing.

As we wrote in our previous post “from what we have heard from our sources Apple had to delay introduction of iPhone 5 because of the new design”. We think that there are definitely two upcoming iPhone models, the cheaper model will be similar to current iPhone 4 and the iPhone 5 will see major redesign. This is our guestimation (like every analyst and journalist have been doing) based on what we have heard from our sources.
