Apple has just announced that iOS 4.3.3 has been released. Of key importance to many is the location tracking feature that will be removed after update to this latest iOS version.
To ensure your iPad or iPhone gets this update, connect your device to your iTunes computer, and click the check for update button in iTunes. Follow the directions given by iTunes and please ensure to unmount your device in iTunes after the update installs and before disconnecting the USB cable.

riccardo,
Normally I don’t advocate jailbreaking or unlocking etc as it voids the warranty. But if this is an important issue to you (it is for many of my readers), Jailbreaking may be your only option:

Be aware that you will not be able to purchase apps from iTunes or the App Store if you take this option and will have to use Cydia.
Kind regards,
Stephen
