T-mobile voicemail hack

Interesting bit today on Gizmodo regarding the recent Paris Hilton T-Mobile voicemail hack. They recommend setting up a voicemail password as a way to block the hackers.
While that seems odd to me, and perhaps a peculiar way to stop a hack like this, I called up my voicemail and set it up. It’s better to be sure. If you’re a T-Mobile customer, try it yourself! (Note that the instructions in the posting may be incorrect for the voicemail system in your area.)
