    Apple only supports the Update or Restore of iPhone 3G to iOS 4.2.1, that is the only Firmware Apple supports for iPhone 3G.

    4.2.1 is the latest iOS that you can install on an iPhone 3G.

     

    Update can be done only by connecting the iPhone 3G to the

    computer with the supplied cable and using iTunes to do the

    update. Over the air or wifi updates are available only in iPhones

    using iOS 5 or later.

     

    Update should not erase your contacts. But as with any OS update,

    backup first. Your contacts should already be in the appropriate

    program on your computer/in iCloud/in Google contacts. If they are

    not already synced somewhere, do so before attempting to update.

    Same for your pictures and anything else that exists only on your

    iPhone without backup elsewhere.
