T-Mobile Website Eminently Hackable?

You can imagine that I was NOT thrilled, as a recent T-Mobile convert, to read this sobering piece. Apparently, the T-Mobile website... the one I have been using to manage my calendar and contacts... is not only hackable, but has been hacked a lot. A sleazy guy actually found Paris Hilton's page and hacked in so that he could view her cameraphone pictures and get all of the information out of her address book. Of course, I doubt there is ANYONE who would find ANYTHING interesting my T-Mobile book. I lead an eminently boring life. Which actually is good for me. No super-villains to battle, no tragic medical condition to worry about. Still, it ain't fun to realize your life could suddenly be an open book.
