If the full file (including addresses) gets into the wild, and I fear that this may happen, it will be a really useful tool for burglars. Many iOS devices probably correlate with many valuables in a home. That's a lot of lawsuits against everybody involved...
Pretty sure that a smart burglar could figure out approximate addresses of people who own iPhones by looking at publicly available Instagram or Twitter or Facebook or Flickr locations. Not to mention people telling the world "I'm camping this weekend" which a burglar hears as "I'll be gone all weekend, steal my things!"
I think a smart burglar would just look at any commonly available database of home sales. Anybody who has moved in the last few years into a more-expensive-than-average house should correlate much better with valuables than iPhones.
However, I'd hope any criminal with brains like that would find something to do that has higher yield and lower risk than housebreaking. I'd suggest working for a private equity company.
Yeah i'm not really worried that burglars are going to use this data-set for harm. If they know about this data-set they likely know about databases of home sales or car sales or just plain old census data listing the average income by county.
