What does this virus do?

Arriving on your phone as the Beta version of a commercially available anti theft program for Symbian handsets, a bug in the program causes it to duplicate itself to the memory card of your device and continuously send SMS messages to a predefined number at your cost. When an infected memory card is inserted into a new phone, the program installs and runs without your permission.
 
SymbOS/HatiHati.A is the detection for the beta version of a commercially available version of an anti-theft Symbian application. A bug in the program caused it to exhibit Worm-like behaviors; the bug has since been corrected in later versions.
