EPOC.Cabir is a proof-of-concept worm that replicates on Nokia Series 60 phones. This worm repeatedly sends itself to the first Bluetooth-enabled device that it can find, regardless of the type of device. For example, even a Bluetooth-enabled printer will be attacked if it is within range.

Well, it was inevitable… fortunately harmless. The smarter the mobile devices get… the more powerfull the worms will be. Protection is required (low memory, low CPU usage a.k.a power consumption) will be needed.
