Researchers Alasdair Allan and Pete Warden have determined that iPhones and 3G-enabled iPads automatically record location information in a file that's backed up to iTunes.

"While the information isn't necessarily accessible to remote hackers, the researchers noted that it does raise some important concerns about privacy," writes Ars Technica's Chris Foresman.

"Warden developed software to view and analyze the database of locations stored by your iOS device, a copy of which is likely sitting unencrypted on the computer with which you sync your iPhone or iPad," Foresman writes. "The pair advised that turning on backup encryption in iTunes is an easy way to protect the information from leaking, though anyone with physical access to your iDevice could potentially access and analyze the database."
