Gadget review: Cellular phones

Nowadays, Modernization occurs in our world, it particularly changes on how we adapt  on a certain modern environment, like for example, the usage of computer, if you don't know how to use computer, you are not completely adapted on that environment.
Speaking modernization, probably the thing that comes in our minds is a cellular phones or cellphones. I remember when I have my first cellphone, the unit of that cellphone is 3310, this kind of unit of cellphone is under new edition wayback past 6 years from now. But, nowadays, that kind of unit is already more likely forgotten by people because of new inventions of cellphone, there's what you call, TS phones, TS is short term for touchscreen cellphones, qwerty keypads and android installed phone. As you can observed, there is a evolution of things because of knowledge of people

On the other hand, there are some facts about cellular phones like what the study says that a person who uses cellphones cannot sleep without his/her phone besides his/her head. I said this is true, because even me, I can't sleep without my phone beside my head but this routine is not good in our head, also in our health because it can inflict radiation to our head that can lead to brain cancer.
