This is another hoax that preys upon people's fear and lack of knowledge of how modern technology works. The type of virus claimed in this hoax is technically impossible.

It is impossible for viruses to spread to cell phones (digit or analog) via telephone calls. The above hoax tries to take advantage that many telephone calls will display "unavailable" and gullible people will mistakenly think they have seen the virus described by this hoax. The Undelivered Mail Virus Hoax tries to take advantage of the same principle.

The hoax tries to establish some credibility by offering a link to some apparently reputable web site (CNET, Nokia, and Motorola) as a (supposed) confirmation. There is (of course) no confirmation of the hoax on these sites. Apparently the author of the hoax assumes that enough people will not follow this lead that by including the it in the hoax, it will give the hoax some credibility. (Even if someone visits the CNET site, they will see so much information, they may assume they simply can't find what is referred to in the above hoax.)

Update regarding recent reports of 'phone viruses'
Please note, that some anti-virus companies in an effort to stir up sales have claimed that viruses have infected cell, WAP, or PCS phones. This is a distortion. In reality all that has happened is that the virus has sent messages to email boxes accessible through the cell phones. Nothing on the cell phones was infected.

This one first appeared in 1999. It may have inspired the Timofonica virus hoax that basically sent out spam to other phones. It did no damage whatsoever. This warning is a variation on the one which appeared in 1999. It is just using our fears against us again. There have been no reports of any new virus affecting cell or mobile phones. That includes CNN.com which I searched just in case and came up empty. There is no virus which damages hardware!

If you get this warning just delete it. It's a hoax.
