    I guess this is a yes, but let's say you jailbreak your phone then a large update comes out. I understand you must un-jailbreak, then apply the update, then jailbreak again, correct?

    What happens to:

    1) Your data?
    2) Anything applied by apps under jailbreak (I guess with this they will simply disappear)
    3) Apps installed when jailbroken

    I did a search online but nothing specific was found, that is fairly recent.

    Thanks in advance :)

    Updating does the un jail breaking.

    You just backup, update, jailbreak again then restore from a backup and you're in exactly the same position you were in before, only you have the updated software.

    Apps bought whilst jail broken are no different to apps bought when on stock firmware. Cud is tweaks have to be downloaded again.

    Keep in mind that the update may not be jailbreakable. Look before you leap or you can lose your jailbreak because the latest update has patched things.

    This is why jailbreaking involves a bit more responsibility.

    While this method will work, I would strongly advise against it. Not only does updating a jailbroken device make you lose about 500MB in storage space, but you will also likely run into stability issues down the line. I always restore as new without restoring from a backup. If you absolutely must keep your data, then backup your jailbroken phone. Restore in iTunes. Jailbreak. Restore backup.

    I've always done it that way and had zero issues. I have sms messages I can't lose so have no other option but to restore from a backup and not set up as new.

    I generally backup the phone, update (if it's a big update I restore using the new firmware but if it's a .1 update I just update). Then I jailbreak then restore from a backup.

    Never had any stability issues at all. I'm running an iPhone 5 I updated to 8.1.1 and rejailbroke right now and have zero stability issues.

    At the iPhone hacks section.
    This is correct.
    If you want nothing but issues and trouble then do not update a JB device.
    Restore, JB and install and sync your stuff back.
    Newbies always want the easy and faster way out and then keep posting threads with problems they encounter.

    I generally have nothing on my phone that I cannot afford to lose. If it's important it may be on my phone, but there is certainly some other place it is as well.

    My pics upload to Dropbox and unlike the user above I don't have anything in my SMS database I can't afford to lose. My contacts are on Google and while a PITA I can always restore my videos from the disks I have and the backups I have.

    With that in mind I generally tend to just restore from a backup as well. If anything goes wrong I can restore (at that point in time) and try again. If I have issues later on that force me to restore to stock, well that's a consequence I have to eat.

    If nothing works, then I will restore as new. Because even though that's more of a PITA, again, I have nothing on the phone I can't afford to lose.

    So far this has actually assisted me as when old tweaks get updated my settings for them come back and I usually don't have to worry about stuff.

    What was really cool once was restoring my iPhone 5 (when I got it) from an iCloud backup that had my data from my iPhone 3GS. Stock I had one blank homescreen and that was because I had an iBlank in that backup that kept that homescreen open for me. That data migrated to my iPhone 5 so I was able to enjoy that without being jailbroken at the time.
