I'm about to update to iOS4.1, and as always I intend to do a clean install. This time around there is some data I really want to save however, so I was reading this tutorial which is for Mac only, but that refers to a iPhone Backup Extractor.

Is there a free and sans-spyware equivalent for Windows? A little google search find this and this for instance, but I don't know if these fit my criteria above.

Many thanks for any suggestions!
