By the end of 2004, the GSM Association reported that over 600 networks in more than 200 countries were serving more than 1.2 billion users (2004).

This paper briefly lists the forensic challenges raised by handsets and overviews the handset analysis techniques used (or usable) by law enforcement officers in the course of criminal investigations.
