Installation note:
This update is only available through iTunes, and will not appear in
your computer's Software Update application, or in the Apple
Downloads site. Make sure you have an internet connection and have
installed the latest version of iTunes from www.apple.com/itunes/
iTunes will automatically check Apple's update server on its weekly
schedule. When an update is detected, it will download it. When the
iPhone is docked, iTunes will present the user with the option to
install the update. We recommend applying the update immediately if
possible. Selecting "don't install" will present the option the next
time you connect your iPhone.
The automatic update process may take up to a week depending on the
day that iTunes checks for updates. You may manually obtain the
update via the "Check for Update" button within iTunes. After doing
this, the update can be applied when your iPhone is docked to your
computer.
To check that the iPhone has been updated:
* Navigate to Settings
* Select General
* Select About. The version after applying this update will be
"3.0.1 (7A400)" or later
Information will also be posted to the Apple Security Updates
