A gadget (a thing, Gizmo) is an article that is innovative and often cleverly designed. Often a gadget is a consumer electronics product (but it doesn't have to be). The technology or design is innovative, so a trendsetter likes to buy it. Often a gadget is also purchased as a status symbol. A gadget is especially interesting at the beginning (and even then it is more frequent for the entertainment purchased, and not so much for its functionality), later there are too many people who have it too, and it is not interesting anymore to have (or to show off). A gadget is often purchased online, in a special gadget or gift shop.

Normally, the hardware (IPhone) is equipped with an operating system with limited capabilities. In the case of the iPhone you can only install applications from the itunes Store, after jailbreaking you can also install applications that are not in the itunes store. Jailbreaking is a fairly harmless process: a number of operating system files are modified (and can be rolled back if desired). The biggest reason to jailbreak is because more is made possible. When the APP store offers enough software, it is not necessary for most people to jailbreak their phone. Https://www.youtube.com/watch?v=zEbCzkcrXJk

After this, it is possible to install other programs (Cydia, Icy, etc.) that make sure you cannot install Apple-approved applications either. Read More
