It was only a matter of time, and now the malicious hacker world has entered the realm of cell phone technology. The Cibir virus has been detected in Symbian OS- based cell phones (including Nokia, Sony and Seimens, according to this  article from NewsFactor.  The virus is spread over a BlueTooth connection, which is a common short-range (30 feet or less) wireless connection between devices like cell phones, PDAs and printers.

More interesting perhaps, is Symantec's announcement that the are now supporting anti-virus software for handheld devices (PDAs) running Microsoft or Palm-OS software. It seems there is now critical mass for supporting anti-virus software on these operating systems, though the current attack ratio is comparitively small.
