Well, as I said before
NUTTY FOLKS: OMG Apple keeps a copy of some wifi stations on my phone. It's a huge privacy violation!
FACT: Apple doesn't access the database cache, emails, passwords, photos on your phone either.
Except, Apple says that they actually do access the location database:
5. Can Apple locate me based on my geo-tagged Wi-Fi hotspot and cell tower data?
No. This data is sent to Apple in an anonymous and encrypted form. Apple cannot identify the source of this data.
8. What other location data is Apple collecting from the iPhone besides crowd-sourced Wi-Fi hotspot and cell tower data?
Apple is now collecting anonymous traffic data to build a crowd-sourced traffic database with the goal of providing iPhone users an improved traffic service in the next couple of years.
