    I have a 4th gen iPod touch and was wondering if I will lose all my data like my contacts, photos, app data, etc if I upgrade to 4.2. I have never upgraded an iPod before so help would be appreciated.

    Also 4.2 still has persistent wifi right, I like having it on all the time so I can receive text messages.

    No. You will not lose your data as long as you (a) update from iTunes or (b) restore from a backup. Still, back up your iPod first. That's a given.

    Yes.

    Only thing you will lose is your music. If you backup and sync regularly, then you will still have your apps and preferences intact.

    A lot of people on here say that app data gets deleted when updating firmware, so I assumed that is what would happen. I don't care if it deletes the songs, as I can just resynch them quickly.

    That's how a firmware update takes place. Everything on the iPod is erased, the new firmware is loaded, and the iPod gets resynchronized.

    It updated fine, the process was easy and everything was still there when I was done updating. I had to press sync to get the music back on there, but that is no big deal. Mine is set to manually manage music too.

    I didn't lose a thing when I upgraded to 4.2 on my iPod touch.

    I have my music set to automatically sync (only videos are manually selected) and use the 128kbs convert option. My music was not deleted (would have taken hours to sync back and it only took around 15 minutes to update).

    Jailbroken? Jailbreaking does nothing. Is there an app like that? Backing up does back up apps' data. You might have to enter the passwords again, though. Were your apps all in the right places when you synced?

    You'd lose all of your Cydia apps and settings when you upgraded from 4.1 to 4.2.

    Yes, I am aware of that, that's why I have AptBackup so that I'll get all my apps back(but not settings).

    I was responding because you had said "Jailbreaking does nothing" in response to "You won't lose any of your data unless you're jailbroken"

    The difference lies in whether you "Restore" or "Update". If you "Update" and you're not jailbroken, everything (music, apps, books, videos, etc.) will remain on your iPod. If you are jailbroken and you choose "Update", you will lose your jailbreak and any unauthorized apps that you got from Cydia or Installous, but everything else will remain on your iPod. When you click "Restore", you're iPod will be restored to the latest version of the firmware and everything you have on your iPod will be deleted, jailbreak or no jailbreak. If you are synced with iTunes though, as you should be, then as soon as your iPod is restored, you can choose to restore the backup to the iPod.

    Not true. My Touch lost all it's music following the upgrade. I assume it needs an extra manual sync which the upgrade process didn't do to restore it. Pictures and apps are fine.

    I upgraded a iPod touch 2G that was running 2.2.1 to 4.2.1 and while it took quite a while to download, reload firmware, resync all data and such everything was there when it finally came back up.
