This might be the first (of many) clue on how the new iPhone 7 should look like. Based on the leaked picture of a drawing on a computer screen, it shows an iPhone case which has rounder corners and no other significant indication. Based on the Chinese character, it seems to say that the iPhone might have sandblasting finish. Usually this process is to make it more lasting.
Some even think that it looks like an iPhone 5C but with metal chassis. What do you think? Apple has sent out an invite on an event on the 21st March 2016. Many do not think that Apple will announce any new iPhone 7 as it is not the usual time frame. There is always the first time. Lets see what Apple has to offer on the 21st March.
