|First, before we even talk about different kinds of cell phones, lets look at some numbers:|
A Little History: Cell phones as we know them today have been in development since at least the late 1940's and the technology developed simutneously all around the world. Most of these early phones were operated out of a vehicle. By 1973 the Motorola Company was ready to develop the first handheld mobile phones in the United States. These early mobile phones are popularly know as "Brick Phones" today. Learn more about that first cell phone and the phones that followed here.
1G, 2G, 3G, 4G: The first analog cell phone systems were introduced in the U.S. in 1978, Isreal in 1986 and Australia in 1987. This first generation system would become known as the 1G network. In the 1990's a second generation mobile phone system was developed (2G). Within the new 2G system there was worldwide competition between the CDMA network that was developed in the U.S. and the GSM network that was developed in Europe. By the end of the 1990's a new cellular system was needed to handle data downloads and internet access. In 2001 a 3rd generation (3G) was launched in Tokyo, Japan followed by 3G network launches in the U.S. and Europe. By 2009 it became clear that existing 3G networks would become overwhelmed by the increasing volume of cell phones so a new 4th generation (4G) network was developed that could transmit data up to 10 times faster than the existing 3G network.

Is it a Smart Phone or a Dumb Phone?: The first mobile phones were just for making calls and they remained as such well into the 1990's. Simultaneously personal digital assistantssuch as the Palm Pilot were being developed throughout the 1990's. With the advent of 3G networks these two technologies could be combined into one device: a cell phone with computer like capabilities and internet access. Thus the "Smart Phone" was developed by taking existing "Dumb Phone" technology (1G and 2G phones) and combining it with a computer like operating system (from PDA's) and internet access (using 3G networks). If you have a phone with limited or no internet access and no operating system it could probably be accurately described as a dumb phone.
PRACTICE ACTIVITY: If you have one of the 6 billion plus cell phones that are one this planet make sure you give yourself at least 10 minutes today to just explore the settings on it. Chances are there are plenty of things your phone can do that you don't even know about.
