Retrievable iPhone numbers mean potential privacy issues
By Dan Moren, Macworld
I admit, sometimes I forget the iPhone is a phone. When a couple voicemails didn’t show up recently, I thought nothing of it until a friend asked me if I’d gotten his message—people just don’t call me that often. But a phone it is, as some users are reportedly being reminded when they get phone calls from the publishers of a free app they’ve downloaded from the App Store.
The application in question, mogoRoad, is a real-time traffic monitoring application available in Switzerland. Several commenters on the store say they’ve received phone calls from the company behind the application after they downloaded the free version, inviting them to shell out money for the full version.
As invasive and despicable as that sounds, it raises another question: how did the company get ahold of the contact information for those users? Mogo claims the details were provided by Apple, but Apple doesn’t disclose that information to App Store vendors. French site Mac 4 Ever did some digging and determined it was possible—even easy—for an app to retrieve the phone number of a unit on which it was installed.
I talked to developers who said that while Apple’s iPhone software development kit doesn’t provide a built-in way to access the device’s phone number, the information can still be indirectly retrieved with relatively little trouble, as this Ars Technica article from January explains. Mac 4 Ever claims that this ability has been around since iPhone OS 2.1.
