i phone to i tunes synching tech help

You might get away with it if you reinstall itunes again but I'm not sure. I thought I'd lost everything a while ago but when I reinstalled it my library was intact.Not sure how it works if you registered for icloud.

I lost 15 playlists the other day and I'm having to manually put them back in. Sorry not much help.

thanks bigmo,just reinstalled i tunes and all ones purchased are there including recent ones downloaded to phone directly.
Does anyone know if possible to send rest of collection from phone to i tunes without having to copy cds again on laptop ?

It can be done, you'll probably need a special program though which you generally have to pay for
