Itunes prep before fresh OS

[Manbatius]

Hi all,

I want to be able to back up itunes before I format my w7 machine and install a fresh install of W8.

I have tried this before when I updated a pc and it sort of worked.

However my iphone 3gs is dead (wont charge, home button and microphone broke)
So the back up on my pc I cannot loose as my phone may be unfixable.

Any guide on how to back up itunes (music not important i have this elsewhere) but everything else to do with the iphone!

Thanks all,

Davey

Thanks all,

I did a combination of the above, including the app data part.
As it is i managed to extract my contacts/ notes from my iphone back up first and that was the main thing.

Will only look into restoring my back ups and installing itunes if i get my iphone fixed.

Someone mentioned de authorising account thats the mistake i didnt do last time!

Also I disabled I cloud, prefer having my own data, though saying that skydrive has somehow got some of my photos, impressive as i have none on this pc and have not used it (that im aware of!)
