If it is a 3GS you cannot update it to 4.3, you can only update it to iOS 6. Install the latest version of iTunes on your computer, connect the phone, click on its name on the left, then click the "Check for Updates" button on the right.
If you can't connect to your home WiFi try rebooting the router.

  • HT4623 How do you update iphone 4 ios version 4.0.1

    My Facebook app was crashing so I deleted it and tried to reinstall it but it says that I have to have IOS 4.3 to install.  I tried getting on FB through Safari and it still crashes there.  How do I update IOS on my iPhone 4? It doesn't have a place to update in the General section.

    You cannot update your operating system to anything other than the current one, which is iOS 6.0.  The safest way to do that is to download it in iTunes on your computer.  After the download is complete, you can connect your phone and update it.  Allow a number of hours for each procedure.

  • How do you update iphone 3gs to the latest software?

    I really want to update the software of my 3gs (currently running ios 4.1). If anyone knows how to, plz reply asap.
    Thanks

    Update it from iTunes on a computer as described at the bottom of this article; devices running an iOS version prior to 5.0 can't be updated straight from the device. It will be updated to the newest iOS release supported by the device’s hardware.
    The maximum iOS version for the fourth generation iPod touch and iPhone 3GS is 6.1.6.

  • HT4623 how do you update ios to 4.3

    how do you update your iphone 3g ios to at least 4.3 so you can use apps.

    Connect your phone to the computer you use for itunes normally, then click on update when you are in itunes , BUT, this will update you to ios 6.0.1 because its the latest update. You can not pick whick update to go to. It will only go to the lateset update, which , by the way, will be compatible with your apps.

    How do you update iPad iOS under Settings/General/Software if the Software button is non-existent?

    You do not have iOS 5 on your iPad so you have to update by using a computer via the latest version of iTunes. You can connect the iPad to your computer and launch iTunes. Select the iPad on the left side under the devices heading. Click on the Summary Tab on the right. Click on Check for Update.
    After you update to iOS 5 or later, you will have Software Update in you settings and can update via WiFi OTA. If you have the original iPad - you can only upgrade to iOS 5.1.1.
