Just like the previous iPhone models and the recently released Samsung Galaxy S2, the rumor-mill trend is progressing fast with numerous leaks coming infront. Recently, new shots have emerged that showcase a comparison between the black and white versions of the next-generation iPhone back.
As it can be seen from above, large portion of the back is made out of metal. The significance of this metal is unkonwn, but it could be deduced that the metal antenna band is molded into the metal backplates.
These images posted by 9to5mac has also been somewhat verified to be true by their well-connected sources which state that same design is being tested internally as well. Gurman, writing for 9to5Mac, explains, citing “sources in position to know” who claim that:
the structure of the shells do match up with what is being tested internally. Namely, the redesigned bottom portion of the iPhone with the moved headphone jack and smaller dock connector are present on at least one of the longer iPhones that Apple is testing internally.
It’s interesting to note that this metal design was initially used in the first iPhone model and ever since then, metal body had long been forgotten. The texture colour would most probably be different since this design colors seem to be somewhat washed out. However, only time will tell if this design is indeed legit or not!.
