Apple iOS 5: How To Upgrade Your iPhone, iPad or iPod Touch in Windows

Today Apple released iOS 5 – the long awaited new mobile operating system for the iPhone (3GS, 4 and 4S), iPad, and iPod touch (3rd GEN and 4th GEN). Follow our groovy upgrade guide here to make sure the upgrade happens seamlessly.

Editor Update – Many users have been complaining of significant battery issues after the iOS 5 upgrade. Checkout our iOS ultimate battery saving guide after upgrading to iOS 5.

To start, make sure you upgrade your system to iTunes 10.5 first.


The most important step of the process is to back up the data on your device. In this example I am using an iPod touch (4th gen) – connected to a Windows 7 PC.  But the backup process is the same for all iOS devices.

Open iTunes and plug your device into the computer. It will show up in the left panel under Devices. Right-click and select Back Up.

Device in iTunes

At the top of iTunes you’ll see it’s backing up your device. If you look at your device, you’ll see the message Syncing in Progress.

Backup Progress

To make sure the backup was successful, you can view the Backup History. Go to Edit >> Preferences.


Now in the Device Preferences window, click on Devices. You’ll see your current backup listed. Click Cancel to close out of the window.

Device Preferences

After the backup is complete and verified, highlight your device. Then click Check for Update In the Version section on the right.

Check for Update

You’ll see a message that a new version of iOS is available. Click Download and Update.


Next a message telling you a backup and restore of your data will be take place. Click Update.


Agree to the software license agreement.


Now wait while the update completes. Here I started my upgrade right after it was released, so it’s taking a long time.

Download iOS 5

You’ll see a series of messages in iTunes while the update happens.

Verify Software

Preparing Restore

Then you’ll see your device has been reset to factory settings. Click OK.

Restored Factory Settings

Your device will be restored from the backup.

Restoring iPod

Then you’ll see your device has been successfully restored. Click OK.

Factory Settings

When it has finished the upgrade, your device will appear in iTunes again. Now you can safely eject it.

Eject iPod

Success! Now you can start exploring the new features iOS 5 has to offer.

Remember, a lot of users will be upgrading during the first few days of the release. If you get an Unknown Error Occurred (3200) – it’s not a problem on your end, but is the result of overwhelmed Apple servers.

      @Fran – What iPhone are you running? Remember — iOS 5 is only supported on the iPhone 3GS, iPhone 4 and iPhone 4S, iPod Touch 3rd Generation and 4th Generation and the iPad and iPad 2.

      If you’re not running one of these, you won’t have the update available to you.

    thanks for this post. i have a 3rd generation ipod touch, 32 gb. when i tried to update my itouch, there was a notification that said the computer desktop’s hard drive only has 4gb and the update process needs 6gb.

    i have an external 1Tb hard drive connected to the desktop, and i have already transferred all my iTunes library into that drive. whenever i open iTunes it’ll only work with the external hard drive connected.

    so… do you know how i would go about pointing the update to the external hard drive, since i still have loads of space there? thanks for any help.

    I just updated my iPod Touch 4th Gen. to 5.0.1. Now every time I sync to iTunes I no longer see a pop-up on the iPod stating: “Sync in Progress.” Also, podcasts I transfer from the iPod to iTunes are no longer removed from the iPod during the sync process like they used to. Could you please tell me how I can get those settings back. I’m using iTunes version

    Any information would be greatly appreciated. Thank you very much.

    I’m wondering if it works for ipod 2g (4.2.1)

    • Gordon Freeman

      Nope! Apple has abandoned the 2nd gen iPod Touch. 4.2 is as high as you can go without jailbreaking.
