Here is how the iPhone was imagined before there was an iPhone
You see, people were not familiar with the all-touch user interface concept back then. Common form factors included flip phones, candybar phones with numeric keypads, and BlackBerry-like smartphones with physical QWERTY keyboards. That's why those who attempted to imagine what the rumored iPhone was going to look like wrongfully used an existing form factor as a reference point. The resulting mock-ups and fake iPhone leaks couldn't be more wrong.
