With more than 1 billion units sold over the last decade, the iPhone has been tinkered with and improved since 2007. Its latest rendition, the iPhone 7, was released on Sept. 16, 2016 -- 9 years after Steve Jobs announced the original Apple iPhone.
To show you just how many changes have been made to the original model, we've compiled a list of major improvements made.
The original iPhone might have been a grand vision, but it was small in size compared to the iPhone 7 Plus. With a 3.5-inch display, the original iPhone is dwarfed by the 5.5-inch screen on the iPhone 7 Plus. Also, Apple offered five colour options for its latest flagship iPhone, but the original device came in one simple colour.
Apple never officially revealed the processor used in its original iPhone, but a teardown from Semiconductor Insights in 2007 indicated it was most likely Samsung's S5L8900. Since then, the iPhone has opted for its own homemade A10 fusion chips, skyrocketing its speed.
Apple discontinued the 16 gigabyte version of the device starting with the iPhone 7, making 32GB the smallest storage option available. That's double the original iPhone's maximum storage option.
The original iPhone's camera is only 2MP, meaning it isn't great in low light situations and can only capture blurry scenes.
It was almost impossible to take a selfie in 2007 also. Apple didn't introduce a front-facing camera until 2010 with the iPhone 4.
