Apple is likely to launch the next iPhone (also known as iPhone 7) in the second week of September and as the launch nears, there are more leaks hinting at the upcoming devices. Earlier this week, we saw an image of upcoming iPhone 7 which revealed the redesigned antenna layout and a significantly larger camera bump. Now the latest leak hints at all the possible colours of the device. The leak images reveals Apple iPhone 7 will be available in space grey, silver, gold and rose gold colour options. Earlier rumours suggested that Apple will introduce a space black variant of iPhone 7 and iPhone 7 Plus but that doesn't seem to be happening this year. [related-post] Samsung and Xiaomi announced its 2016 flagship smartphones in all black colour variants and Apple was widely rumoured to follow the move. The latest leak from MacityNet, however, refutes that possibility. Apple already offers a jet-black variant of Apple Watch branded as Space Black. The latest leak hints at existing styles being retained for the next generation iPhone. Apart from the colour variant, the latest leaked images also strongly complement the rumour of larger camera bump and smoother antenna design. While the antenna redesign looks fine, that camera bump might not go down well with iPhone users.
