These older versions may still be distributed on file-sharing networks and free software download web sites.

In July 2004, computer hobbyists released a proof-of-concept mobile virus named Cabir. This virus replicates itself on Bluetooth wireless networks.

In March 2005 it was reported that a computer worm called Commwarrior-A has been infecting Symbian series 60 mobile phones.
