The iPhone is Apple’s first cellular phone, and it was introduced during a keynote speech by Steve Jobs during the Macworld Conference and Expo in 2007. The iPhone was initially a sleek black rectangle, but Jobs later added an interactive feature that allowed you to unlock it by sliding your fingertip across the screen. The arrow moved when Jobs pressed it, and some people said that the interaction of a human finger and an image on the screen was more impressive than all of the other features combined.
The iPhone uses a touchscreen that recognizes complicated gestures. For example, you can zoom in or out by spreading your fingers across the screen. This feature is useful when you want to read the screen more easily. It is also available in portrait or landscape orientation. You can switch between the two modes based on your preference. Alternatively, you can set your iPhone to be readable at different distances. Whatever your preference, you can find a perfect solution for your needs by following these steps:
The iPhone is compatible with all kinds of cellular networks, and is easy to use. It has a GPS receiver so you can find your way with a few taps. You can also use it to view maps from Google Maps or satellite data. Before the third generation, you could upgrade your iPhone with a 2.0 software update, giving it new functions. However, the older version did not have a GPS receiver, and did not support the 3G network.
