    I've recently jailboken my 3.1.3.

    I know the new update is due out today.

    If i open Itunes when its available and lclick update, will i lose my apps or music?

    I have just this minute right clicked my ipod under itunes and selected backup.

    What i basically want to know is, When i update will i lose all my apps and music? I know my jailbroken apps will dissapear, but will the ones i've bought?

    Updating doesn't touch your stuff (Music, apps) but you may want to backup just in case.

    I'm not so sure about data backup as I normally restore rather than update but i think this may help a bit.

    If you click on Updating your iPhone, iPad, or iPod touch and at the end you can see this line.

    "* Updating your device does not affect user content or settings."
    Does that mean apps and music wont be deleted? I'm unsure of this

    Hope someone more experienced can shed some light on this issue.

    Updating touches nothing except the firmware. It update the firmware, leaving all user data intact - media, settings and all.

    Restoring on the other hand wipes your iPod clean, restoring it to factory default settings. You can get your media back onto the device by syncing with iTunes, but I'm not sure about any user data.

    Ok, I'll go ahead and update then.

    If ive backed my ipod touch up, and it does somehow delete the media etc. Would using the backup re-instate everything, ith the new firmware still intact?

    'Restore from Backup' should put everything back onto the iPod while staying on iOS4. However, even after the restore, you will still have to sync with iTunes to get your Music, Videos, Apps and everything else that syncs with iTunes back onto your iPod. It's quite a lengthy process.

    Ok, does this mean I can upgrade from my 3.1.2 Jailbroken iPod touch 2G to a legit 4.0 with itunes, then use redsn0w to jailbreak it again without losing data?

    Thought i'd post in here instead of starting a new thread as it is related.

    Nope. If you are jailbroken, you must restore to factory default before jailbreaking. So 3.1.2 JB -> iOS4 -> iOS4 jailbroken. Sadly, it involves restoring to backup, and lengthy sync cycles.
