– On a Mac, this can be accomplished by clicking the Apple Logo and selecting Software Update… – In Windows, this can be done using the path Help step, and it will prevent several possible upgrade issues.
Most current i OS users will want to do an upgrade install, as it is the most simple and quickest way to get i OS 5 up and running on your device. Other devices such as the i Phone 3G, i Pad, and i Pod Touch should follow the same procedure.
Upgrading to i OS 5 from an earlier i OS version such as i OS 4 is a fairly simple task, but it’s also a major update, as it installs a whole new operating system, not just incremental fix updates that Apple often releases for their i Devices.
This means that the update will take considerably more time, but it will be worth it because i OS 5 offers several new features, including the highly anticipated Wi-Fi sync.
When you connect your device, i Tunes will need to sync the apps, media, etcetera to the device, so wait for the sync to complete before you proceed.
Once the sync is complete, select your device from the left-side navigation pane in i Tunes.
From here, i Tunes will automatically connect to the i Phone software update server and begin downloading the update.
