Cellphones have become our entire lives now. We do not get separated even a minute. If you ever lose your cell phone, you feel like you have lost your entire life. The reason is that smartphones are too smart sometimes that we do not carry anything else but them. The reason is that we can use it as a map, camera, bank, dictionary, etc. The last thing we use them for is phones now. It is very funny but true. On the other hand, since we use them a lot, we can customize them with great ideas. You can craft cases or very useful items for your phone.
