Released in 2007, the original iPhone has a storage capacity of 4 GB, 8 GB, and 6 GB. It was a revolutionary advancement because it had a unique design that laid the foundation to smart phone technology. Back then, the App Store was non-existent, meaning third party apps could not be downloaded.

The iPhone 4 was a major upgrade and redesign compared to its previous model, the iPhone 3GS. This model had much higher processing speed and resolution. Apple added a front-facing camera and the apps FaceTime and Game Center during this release.

Released with the iOS 6 software, the iPhone 5 redefined the iPhone by enlarging the screen and updating the camera capabilities. Pictures were improved through the addition of autofocus and face detection and users were now able to add geotags to their photos.

The iPhone 6 was a technological breakthrough. It had a larger screen with better screen resolution, a clearer camera than previous generations, and a longer battery life accompanied with a faster processing chip. This iPhone also introduced Touch ID to streamline and personalize security.

As Apple’s newest product, this iPhone has the same capabilities of the iPhone 6S, but reverts to a smaller size. This is significant because Apple was able to kept the processing capability even with a decrease in size. This amazing feat of technology will be in stores at the end of May.
