According to a report from iMore , the design of the sixth generation iPhone has not yet been finalized by Apple yet. It says that the tech giant is still playing with prototypes of iPhone 5  and its final form factor has not been set in stone.

The report says the handset won’t bear a giant screen and its aspect ratio will not be increased to 16:9 . iMore’s sources also claim that Apple will not be utilizing metallic cover for the sixth generation iPhone. The tech giant is still planning on using a smaller dock connector for the next iPhone and the handset won’t lack a physical home button (probably). Because of the long prototyping process that Apple believes in, we have been hearing inconsistent and contradictory news from sources in Apple’s supply chain.

It says:

Sometimes there are more audacious and more conservative prototypes, with the final choice coming down to component costs and device tests… Keeping the Home button also necessitates certain design trade offs (everything has an opportunity cost) when it comes to overall device size and screen layout.

It also adds that even if the company alters the handset’s screen size, it won’t make it bigger than four inches. So, the aspect ratio of the screen display will remain unaffected. The iPhone 5 is still on the track of October release .

Earlier, iLounge claimed that Apple will be incorporating a smaller dock connector in iPhone 5 and said that the handset will be thinner and longer than the current generation iPhone. This design tweak, as assumed, would require alteration in the aspect ratio of the screen. Utilization of liquidmetal technology for iPhone’s back cover has also been in talks lately.
