1. Early mobile phones

2. Annoying mobiles

3. Expensive mobiles

4. Fashionable mobiles

5. Multifunctional mobiles

6. Modern mobile phones

A. Lars Magnus Ericsson, was the first man who had a telephone in his car. When he saw a place where he could get to phone lines, he connected to them with a pair of long electric wires. Then in Russia two Soviet engineers successfully tested a mobile phone installed in a car. It could connect to a local telephone network within 20 kilometers. A year later, two engineers from Europe tried to use antenna in the phone.

B. The company of mobile phones in Finland started to sell their products in 1970. There were several types of phones: 2G and later 3G. Third-generation phones are now used everywhere in the world. They are small, flat and very comfortable to use. Some people say that the only problem with the new phones is to remember all the functions. The mobile phone is often called the Seventh of the Mass Media (with Print, Recordings, Cinema, Radio, TV and Internet the first six).

C. In many countries, most adults and many children now have mobile phones. Mobile phones are used for a variety of purposes, including keeping in touch with the family, running business, and for emergency calls. Children and adults often play mobile phone games or use the phone as an audio player. In Japan, phone companies provide immediate notice of earthquakes and other natural disasters to their customers free of charge. In the event of an emergency, disaster response crews can find injured people using the signals from their mobile phones.

D. Today’s mobile phones do more than just offer voice, email, Web and music services. They are stylish accessories, too. Cool design has always played a great role in digital business. People, young people especially, use the phone to express their self. Just like clothes, phones can carry a message of sports lifestyle, luxury, adventure or romance. Mobile phone companies introduce their new collections every season and it’s rather difficult to keep up with today’s mobiles.

E. Mobile phones have increased greatly in the world. Some people carry more than one mobile phone for different purposes, such as for business and personal use. The mobiles are to be seen absolutely everywhere – in schools, restaurants, theatres and even churches. They ring during lectures, meetings and in classical music concerts. In recent survey, 62 % of people said that the most irritating thing in their lives was mobile phones on the train!
