I am using an iPhone 3GS that is jailbroken and uses iOS version 4.1. How can I update my phone to the latest version?

    Back up your phone.
    Un-jailbreak your iPhone. (Reset to factory settings in your settings menu.)
    Update with iTunes.
    Re-jailbreak your phone.
    Restore your backup.
    Enjoy the rest of your day!

    Basically you would need install the image, IPSW, for the latest firmware that has been released.
