More celebrities are becoming fair game for hackers who find their way into the personalities' smartphones or PDAs and make really private stuff public. We all know about Paris Hilton's hacked Sidekick. And it's rumored that Lindsay Lohan got hacked for the second time, with her private pics making the rounds. A local beauty queen became famous for the compromising pictures taken from her stolen smartphone.

The lesson is always there, but people never seem to learn it. The potential for anything on your smartphone or PDA becoming public is greater, because these gadgets are easier to steal or lose. And let's not forget that it's so easy to pass things around thanks to the Internet.

Which is to say that you should never leave anything really embarrassing on them, unless you won't mind everybody knowing about it. Fantasia Barrino strikes a good compromise. If the rumors about her own hacked cell phone pics are true, then at least she didn't pose in her birthday suit.
