A hidden iPhone tracking software was detected by researchers after the latest software update in June 2010. The software came along with the update and logs users´ whereabouts via GPS.
The locations are then saved on a map which shows where the users went on each day, dating back to June 2010. The data is stored on the iPhone and iPad 3G and on every computer the device is synced with.
It is not clear yet, whether the data was also sent to Apple. So far, the company has not commented on the issue.
