Have anything sitting in your voicemail that you'd prefer the rest of the world didn't hear? When's the last time you went about checking it, anyway? AT&T is now on a mission to save its carefree customers from themselves, and beginning today, all new subscribers will be required to set a voicemail password or affirmatively disable the security measure. Ma Bell's new policy is a reaction to the current unauthorized intrusion hubbub in the media, combined with the very real threat of caller ID spoofing. Shockingly, its current customers won't receive similar treatment until early next year, and only when they upgrade their handsets. Of course, you can easily secure your voicemail within the settings, and if you prefer the convenience of retrieving your messages without hassle, you'll still have that option -- much to Rupert Murdoch's pleasure, that is.
