The unprotected location history file in iOS 4 has drawn attention from Minnesota senator Al Franken, says CNN. Franken has reportedly sent a two-page letter (PDF) to Apple CEO Steve Jobs, arguing that the file represents a potential security threat. "Anyone who gains access to this single file could likely determine the location of the user's home, the businesses he frequents, the doctors he visits, the schools his children attend, and the trips he has taken over the past months or even a year," part of the letter reads.
