Here's a guide that explains exactly how to get the latest i Phone software on your i Phone.
Apple delivers its i Phone software updates through i Tunes, so the first thing you should do is make sure you have the most recent version of i Tunes running on your computer.
You can download it if you like, but you don't need it to update i Tunes.
Once the i Tunes update has downloaded, it will begin installing itself automatically.
To make sure that your i Phone is running the latest version of the i Phone software, you'll need to connect it to your computer and download the update using i Tunes.
But don't worry: the process is pretty painless.
To update i Tunes, go to the "Help" menu, and select "Check for updates." If i Tunes says you have the most recent version, you're all set to move on to Step Two.
Upgrading to a new version of the i OS used to mean that you had to be in front of your computer, had to connect your i OS device to it, download the update to your computer and then install the update via syncing with i Tunes.But if you have i OS 5 or higher, that's not true anymore.Did you know that Apple often updates the i Phone operating system, adding new features and cool new tools?When the installation is complete, you may need to restart your computer in order to run the new version of i Tunes.
Accept all prompts necessary to install the updated software.
Note: Apple's updater is likely to suggest additional software that you can download (such as the Safari browser); none of this is necessary.
