We've just learned that the 29A virus group has released the original source code of the Cabir.A phone worm.

Some comments in the Cabir.A source code include:

Bluetooh is free, and the receiver will be a apropiated target. The problem is bluetooth needs to have near the target (10 meters radio). Progagation scenaries will be trains,restaurants, etc...
