State and local law enforcement officials responding to emergencies and criminal complaints almost inevitably discover the presence of a cell phone. Any technology that can be used for legitimate purposes can be used to accomplish illegal aims as well. Small external media placed inside the phone can hold up to 6 gigabytes of information. Now, data come and go using wireless data transfer coupled with Bluetooth®, infrared, and propriety or USB data cables that connect directly to a computer. Within a few years, features such as voicemail and text messaging became available. Cellular phones were communication devices that supported wireless voice transmissions as two-way full-duplex radios.
Early cellular phone technology (circa 1984) featured very little functionality. Cellular phones can perform all of these tasks and more: voicemail, music/MP3 player, camera, video camera, voice recorder, Web browser, e-mail appliance, text/instant messenger, address book, calendar, notepad, and games. He functionality of cellular phones today rivals that of personal digital assistants (PDAs) and even laptop computers.
