Apple released an update to iOS 4 that addresses some concerns over a file that stores location data. (BRENDAN MCDERMID)

The iOS 4.3.3 update reduces the size of a crowd-sourced location database stored on individual devices, stops the file from being backed up on iTunes and deletes the file entirely if a user disables location services.

Apple promised to release the update in a Q&A a week after Pete Warden and Alasdair Allen published their report on the location date problem. The company also promised that the file would be encrypted in the next big iOS release.

The update is available through iTunes.
