Got an iPhone or 3G iPad? Apple is recording your moves
Today at Where 2.0 Pete Warden and I will announce the discovery that your iPhone, and your 3G iPad, is regularly recording the position of your device into a hidden file. Ever since iOS 4 arrived, your device has been storing a long list of locations and time stamps.
Context & Ripple Effects
The question of what Apple quietly collects from its phones has been open since at least November 2007, when iPhone usage-data collection was first raised. Pete Warden and his co-author turned suspicion into demonstration at Where 2.0 on April 20, 2011: any iPhone or 3G iPad running iOS 4 has been keeping a hidden, timestamped log of the device's positions.
The story travelled fast — the Guardian and Andy Ihnatko both picked it up the same day. The timing sharpens the contrast: the same day's coverage has Apple posting record fiscal Q2 results on 113 percent year-over-year iPhone sales growth, meaning tens of millions of newly shipped devices are carrying the logging behavior into the market.
First-order effects
- Every iPhone and 3G iPad user on iOS 4 is walking around with an unencrypted, years-deep location history on their device — and on any computer they sync to via iTunes backup.
- Apple is forced to explain, publicly and quickly, why the file exists, what it transmits, and how to disable it — a question its own support channels had not answered.
Second-order effects
- Security researchers and forensics vendors gain a new data source: tools that extract the file make an owner's movements readable by anyone with access to the phone or its backups.
- Rival mobile platforms face immediate pressure to disclose their own location-logging behavior, since 'everyone does this' becomes the obvious defense and must be verified.
Third-order effects
- If undisclosed device telemetry keeps surfacing, carrier-independent location logging moves from engineering footnote to regulatory subject — consent, retention, and encryption defaults for sensor data become the terms on which mobile platforms compete.
- The episode establishes a template for accountability: independent researchers demonstrating behavior at industry conferences, rather than vendor disclosure, becoming the mechanism by which consumers learn what their devices record.
The trend: Smartphones are becoming always-on location sensors whose data trails are being documented by independent researchers faster than vendors disclose them, pushing location privacy toward a defining consumer-protection issue for the platform era.
