Paris Hilton Sidekick hack:breach, blunder or brilliant marketing?

There is a lot of discussion going on about the hacking of Paris Hilton's Sidekick. There seem to be four trains of thought:

1. The bimbo gave out her password or used a weak one. Or was it socially engineered from her? At least, that's what T-mobile should be praying.
   
   
2. This was part of Nicolas Jacobsen's original hack, just now coming out in the clear. Or perhaps it was the same person who hacked her blackberry last month?
   
   
3. This is a new hack - the worst possible case for T-mobile.
   
   
4. This is a publicity stunt or attempt at viral marketing - she is a spokesperson for T-mobile after all. And they are selling the Sidekick II for $100 off.....

What's your take? My guess is social engineering or an aftershock of a previous hack, but it will be interesting to see how it shakes down.

The final word is that it is an excellent warning that if you put your confidential data in the hands of a 3rd party, it's safety is totally out of your hands.
