iPhone tracking practices, for example, continued to come under the microscope, prompting the company to

issue a statement

on Wednesday.

"Apple is not tracking the location of your iPhone. Apple has never done so and has no plans to ever do so," said the release. Apparently, Apple doesn't track iPhones -- it collects the data from WiFi and cell tower antennas that track iPhones.

Apple's iPhone tracking was in the spotlight this week.

Nonetheless, Apple vowed to issue new software that cuts back on the location tracking and also let users opt out of it.
