The “4” in “iPhone 4” could imply 2 things – Firstly, it is the fourth iPhone incarnation. Secondly, it offers a resolution four times that of the previous iPhones! Moreover, this matches the new operating system that it features too – the iOS4. Hence, the '4' does not actually refer to “4G” like most of us assumed initially.
