To see how much space you have available on your i Phone, tap the "Settings" icon, choose "General" and select "Usage." If you don't have at least 1.4GB of available space, you need to clear some items off your phone.

On a Mac, choose "Check for Updates" from the i Tunes menu.

On a Windows machine, the option is in the Help menu.

When downloading and installing the files over a Wi-Fi connection, the update may fail to complete if the i Phone battery is low; plug it in to ensure steady power during the update.

If your Wi-Fi signal is unstable or too slow, the update may also fail.

Be sure that you're downloading over Wi-Fi and not via 3G or 4G, or you may end up running out of data.

If you previously tried out a beta version of i OS ahead of its full release, you should note that in order to get upcoming i OS releases you will need to remove the Apple configuration profile from your device.

Released in September 2013, i OS 7 was immediately available for the i Phone 4 and newer i Phone models.
