iSpy?

"Your iPhone is keeping a record of everywhere you've been since June. This data is stored on your phone (or iPad) and computer, easily available to anyone who gets their hands on it. Why? Apple won't say. We're creeped out.

The enormous privacy startle, apparently enabled by June's iOS 4 release, was discovered by two security researchers, one of whom claims he was an Apple employee for five years. They're equally puzzled and disturbed by the location collection: "By passively logging your location without your permission, Apple have made it possible for anyone from a jealous spouse to a private investigator to get a detailed picture of your movements," they explain. All it would take to crack the information out of your iOS device is an easy jailbreak. On your computer, the information can be opened as easily as JPEG.

The data itself is jarringly accurate. Even though it appears to rely on tower triangulation rather than GPS pinpointing (meaning you're not safe with location services switched off), the map I was able to generate with mapping software the security duo released visualizes my life since the day I bought my iPhone 4 in July. Everywhere I've been. Bus trips home. Train trips to visit family. Vacations. Places I'd forgotten I'd even gone. My entire personal and professional life—documented by a phone I didn't know was also a tracking device. It's all accessible—where I've been, and when. I don't want this information bouncing around in my pocket with me. Do you?"
