If you turn off automated and user-initiated software update checking in iTunes, you’ll need to distribute software updates to users for manual installation.

To update iTunes, download the latest iTunes from http://www.apple.com .

To update iPhone OS, follow these steps:
1 On a computer that doesn’t have iTunes software updating turned off, use iTunes to download the software update. To do so, select an attached device in iTunes, click the
Summary tab, and then click the “Check for Update” button.
2 After downloading, copy the updater file (.ipsw) found in the following location:
On Mac OS X: ~/Library/iTunes/iPhone Software Updates/
On Windows XP: bootdrive:\Documents and Settings\user\Application Data\Apple Computer\iTunes\iPhone Software Updates\
3 Distribute the .ipsw file to your users, or place it on the network where they can access it.
4 Tell your users to back up their device with iTunes before applying the update. During manual updates, iTunes doesn’t automatically back up the device before installation.
To create a new backup, right-click (Windows) or Control-click (Mac) the device in the iTunes sidebar. Then choose Back Up from the contextual menu that appears.
5 Your users install the update by connecting their device to iTunes, then selecting the Summary tab for their device. Next, they hold down the Option (Mac) or Shift
(Windows) key and click the “Check for Update” button.
6 A file selector dialog appears. Users should select the .ipsw file and then click Open to
begin the update process.
