Today at Where 2.0 Pete Warden and Alasdair Allan will discuss 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. We’re not sure why Apple is gathering this data, but it’s clearly intentional, as the database is being restored across backups, and even device migrations.

Alasdair Allan is the author of Learning iPhone Programming and iPhone Sensor Programming published by O’Reilly Media. He is a senior research fellow in Astronomy at the University of Exeter, and as part of his work there he is building a distributed peer-to-peer network of telescopes that, acting autonomously, can reactively schedule observations of time-critical events and carry out complex long term monitoring of variable objects. Notable successes include contributing to the detection of the most distant object yet discovered, a gamma-ray burster at a redshift of 8.2. Alasdair also runs a small technology consulting company writing bespoke software, building open hardware and providing training. He sporadically writes blog posts about things that interest him, and more frequently provides commentary about them in 140 characters or less.
A former Apple engineer, Pete Warden is the CTO of Jetpac, and writes on large-scale data processing and visualization
