Mobile phones have come a long way since the early 1980s when they were the size of a block and weighed basically the same amount. Nowadays, mobile phones are equipped with built-in cameras, polyphonic ringtones and high-tech games. The new 3G mobile phones are also capable of downloading full motion video and full spectrum music. While there were few mobile phone manufacturers in the 1980s, there are now many. In addition to manufacturers like Motorola and Siemens, today's phones are manufactured by Sony-Ericsson, LG, Toshiba, Samsung, Hitachi, Danger, Palm, HP and others.

As the use of wireless phones around the world increases, the old CDMA and TDMA standards are replaced by GSM, the worldwide standard outside of North America. Relatively new mobile phone companies, such as Vodafone and T-Mobile in Germany and NTT DoCoMo in Japan, have benefited from the increased use of mobile phones as their mobile offerings and offerings expand around the world . . In addition, are traditional IT companies moving or moving in the cell phone industry? PalmOne manufactures the Treo 650, HP comes out with its own PDA smartphone and Microsoft manages the operating systems of many of the latest cell phones apps on the market.

In addition to being used as a method of wireless voice communication, cell phones have been transformed over the last decade into mobile computing platforms. These new cell phones are powerful enough to power many applications that a few years ago needed a desktop station.

Along with technological innovation and greater adoption around the world, prices for materials and services have steadily declined over the past decade. While only a few years ago, most cell phone service providers were demanding three-year contracts with heavy fines for early cancellations, we can now get a free, next-generation phone with a new contract. only one year.

In addition to cell phone equipment, new industries have emerged to meet the needs of cell phone users who need accessories such as cell phone covers, screen protectors and ringtones. Similarly, the jargon of SMS (simple messaging system) and MMS (multimedia messaging system) is slowly entering the society of vernacular cell phones. The use of abbreviated abbreviations in LOL (laugh aloud), in SWAK (sealed with a kiss) and in G2G (it will be done) has become second nature for teenagers who are the main users of telephone messages.
