[00:01.26]Mobile 1 phone technology has advanced
[00:03.63]at an incredible 2 rate in the last few years.
[00:06.57]The first generation (1G) mobile phone system
[00:10.03]was developed to make
[00:11.35]and receive telephone calls anywhere
[00:13.32]within the mobile phone network.,
[00:15.78]Then came the digital revolution
[00:17.82]and 2G mobile phones could also be used
[00:21.01]for sending text messages (SMS).
[00:24.13]What this meant was that mobile phone users 3
[00:25.84]could use SMS as a cheap means of keeping
[00:28.92]in touch.According to one website,
[00:31.94]China began using SMS in 2000
[00:34.79]and growth has been amazing.
[00:37.07]From a little over 1 billion messages in 2000,
[00:40.25]220 billion SMS messages were sent in 2003.
[00:46.28]Recently developed 3G technology has enabled 4
[00:49.06]new features to be added to mobile phones.
[00:52.56]One such feature is a tiny camera
[00:54.36]in the phone that enables 5 tha sending
[00:56.37]of photographs and video images.
[00:59.55]Another development that has been added
[01:01.08]is WAP technology that allows you
[01:03.50]to access the internet from your phone.
[01:06.24]At present, however, WAP technology
[01:08.40]is more expensive than using a computer
[01:11.28]but this is sure to change.
