    I'd like to know if it's possible to update a jailbroken iphone to a newer version rather than restoring and then jailbreaking it again. I know you can backup and then restore your iphone to the latest version and then jailbreak again if there is any available, but I just don't like to re-register my fingerprints, re-add my cards to passbook, and set up all the other settings all over again.
    so for example if I'm on IOS 8.3 (jailbroken) can I update to 8.4 through iTunes and then jailbreak again?

    Well, assuming that the update you go to is jailbreakable the answer is yes. You can always update. You cannot always update and jailbreak.

    Nothing above 8.1.2 (including 8.3 and 8.4) is jailbreakable right now.

    OK great. so for instance if I jailbreak the 8.4 in the next few weeks, and then 9.0 comes out in September(jailbreakable), I can simply update to 9.0 in Itunes and not restore?

    I went back and reread your initial post. I misread your post (I read it backwards).

    What you want is not possible. You have to re-jailbreak each time you update.

    So, yes, you can update to iOS 9, but you lose your jailbreak.

    If you're running a jailbroken iPhone you can't use the Update function in iTunes to go to a newer iOS firmware. When you install the jailbreak it re-arranges some system files. Once this is done you can't update the firmware any longer as an update would require the system files to be in default order.
    The only way to update to a newer firmware is by using the Restore function from iTunes. During the subsequent set-up of the iPhone use restore from backup which will bring back your data and most of the settings, i.e. no need to manually set-up all your settings again.
    Of course, you then also need to install the jailbreak (if available) on the restored iPhone again.
