Responding primarily to its recent location tracking controversey, Apple on Wednesday released iOS 4.3.3, the latest update to its mobile operating system. The update includes the following fixes and changes for iOS-based devices:

- Reduces the size of the cache.

- No longer backs the cache up to iTunes.

- Deletes the cache entirely when Location Services is turned off.

The update is recommended for all users of the GSM iPhone 4, the CDMA iPhone 4, iPhone 3GS, iPad, iPad 2, and the third and fourth-generation iPod touches. To download and install it, connect your device to your Mac or PC and click Check for Updates in iTunes.

If you’ve tried the update and noticed any changes (for better or for worse), please let us know in the comments.
