    Hello there ,

    I know that there have been much threads about these , and I know the Google search has my answer ,

    But I really need a quick and reliable comment about my current state -

    I have an ipod 3g , running on Jailbroken 3.1.2 , I have downloaded 4.0 software from http://www.felixbruns.de/iPod/firmware/ .
    Could I upgrade my iPod from the current state , to 4.0 without losing all my data - Music , Apps , etc .. with the Shift+update method ?

    This is extremely important to me , my music library is used for personal business - I have no backup of it whatsoever (1500~ songs) .
