For iPod Touch users who did not purchase the 3.0 software update for $10, it remains to be seen as to whether or not you can still upgrade to iOS 4 for free.

How to Update your iPhone or iPod Touch

I find that the simplest and quickest way to update my iPod Touch is directly in iTunes. Using three easy steps, this guide will show you how to update your device using iTunes. I am using a Mac, but the same thing can be done using Windows.

Step 1. Ensure you are running the latest version of iTunes.

  1. Open iTunes.
  2. Click on iTunes>Check for Updates… in the menu bar.

  3. If an update is available, a pop-up will appear. Click Download iTunes.
  4. This will open Software Update. I would recommend that you download all the available software updates, but you may also deselect everything but iTunes. Once you click Install, the update will perform automatically.
  5. If you have not already, quit out of iTunes.
  6. Once the new version of iTunes has downloaded, Agree to the License Agreement that pops up. Note that sometimes, your computer may need to be restarted in order for the new version to launch. If prompted, restart your computer.
  7. iTunes should automatically launch, running the newest version.

Step 2: Connect your iPhone or iPod Touch to your computer.

  1. If it is not open already, open iTunes
  2. Connect your iPhone or iPod Touch to the computer via the USB port and the cable that came with your device.
  3. Your device’s name should appear in the side bar of iTunes.
  4. By default, your device is set up to automatically sync with iTunes. This may take a while, as the device needs to be backed-up in addition to syncing.

Step 3: Update your iPhone or iPod Touch’s software (iOS 4 available June 21)

  1. Click your device’s name in the sidebar to bring up this screen.
  2. Under the Summary Tab, click the “Check for Update” button under Version
  3. If an update is available, click Update.
  4. This download may take a while. Make sure not to disconnect your device or quit out of iTunes. Various prompts may appear once the software is downloaded. Click Accept or Continue for all prompts. Included in this will be the License Agreement, in which you must click Accept.
  5. If the update is successful, under Version, it should say “Your iPod (iPhone) is up to date. iTunes will automatically check for an update again on (insert date).”

There you go. You have successfully updated your device to iOS 4. Enjoy!

    i'm running itunes 9.1.1 but when i select my iphone and click update (my button isn't called 'check for update') on the summary tab i just get a pop-up that my version of itunes is the latest version – nothing about the iphone software at all

    any suggestions? thanks in advance

  6. blcnyc24 says:

    never mind i figured it out. even though the version check in itunes said 9.1.1 was current, the software update suggested 9.2 – after that 4.0 downloaded

    thanks anyway

  7. Jt says:

    Does anyone know of a way to force this install on a first gen iPod touch? Even if it doesn't have the horsepower to multitask, I would like some of the other features.

  8. Snouty says:

    Oh my, everything went well until it rebooted the 2nd time then itunes said “Cannot restore your ipod because the password was incorrect” Now I have a dead ipod touch :(
    Oh I never set a password so I don't know what it could be :(

  9. Joe says:

    try '0000', since that tends to be the default lock on mobile devices

    I need help with my iPod touch !
    I tried updating it & everything was fine until a window popped up saying
    “Windows needs to install driver software for your Apple Mobile Device (Recovery Mode)”
    then it gives me 3 options:

    1) Locate and install driver software (recommended)
    -windows will guide you through the process of installing driver software for your device.
    2) Ask me again later
    -windows will ask again the next time you plug in your device or log in
    3) Don't show this message again for this device
    -Your device will not function until you install driver software.

    What Do I Do !?
    I NEED SERIOUS HELP
    My iPod won't go back to its normal mode,
    on my iPod's screen all I can see is the USB cable pointing up at the iTunes logo.
    I can't get out or nothing.
    ;(

    I installed iOS4 last night, and today I downloaded a full album from itunes over the 3G network, and it showed all the songs going through the download process. When it was done, I was expecting to see the songs on my ipod on my iphone, but I did not see them, and they were not in my purchased folder in itunes. I tried to buy it again to see if there was an issue with the first download, but it said that I had already purchased this album, but would I like to buy it again. Really???? I cant even see the one I purchased the first time around. iOS4 glitch?

  12. lfcanishlfc says:

    pls pls pls reply ASAP
    i checked for update on my ipod touch 2g and it found it, so i downloaded and it successfully downloaded.
    however it did not install because as it was backing up it said 'not enough memory on hard drive'. i.e. it was interrupted.
    the next day i replugged my ipod and it said install, so i clicked it but it is taking so long, ive been trying days but the same thing happens. is this because the original 'download and install' was interrupted?

  13. Kkeckler says:

    How long should it take to backup/sync your iphone??? Mine has taken forever. I don't know if it is the update taking forever or the sync but it is getting annoying and I don't know how patient to be!!!

  14. Kbworkit says:

  15. Jewar3086 says:

  16. Jhovs says:

    How can i save my voice memo's in my PC

  17. Mazzamrulz says:

    I NEED HELP PLEASE. I go to download (I have updated iTunes to 9.2, and I have the Update option) and it starts downloading. A few minutes later, I get a pop-up saying “There was a problem downloading the software for the iPod 'Nicole's iTouch'. The network connection timed out. Make sure your network settings are correct and your network connection is active, or try again later.” Error 3259. My network is fine…

  18. Sebnem says:

    I have the same problem, could you please let me know if you've sorted out the problem or not? If yes how?

    Thanks,

    Sebnem

  19. Sebnem says:

    Oh well, I found the reason why I couldn't update it: It was because of my Kaspersky virus programme blocking the update. So when I shut it down, the update process started and it is now sorted. How simple the solution is. Can't believe I couldn't think about it 15 min ago.

    Anyway thanks again…
