The iOS was upgraded from 6.1.2 to 6.1.3 and the ADSL disconnected part way through the upgrade and I lost all my contacts, photos, settings etc. Below is the error message that occurs every time I try to restore from my iTunes backup. Even when I try to restore from older backups via Time Machine, this error message still occurs.
Error message:
iTunes could not restore the iPhone "X iPhone" because the backup was
corrupt or not compatible with the iPhone that is being restored.

Presuming you already have a valid backup of the iPhone, give phoneMiner a try (trial download on their site). It will scan for any previous backups and if they exist allow you to extract your contacts/photos etc.
