"The backup of choice if you need to upgrade your iOS"
This backed up each of my iPhone contacts to my PC and was able to restore them after I upgraded to iOS 5
not much to say here
I have been planning to upgrade my iPhone to iOS 5 for a long time now, but have always hesitated due to horror stories I heard of iTunes loosing backed up data and friends ending up with their iPhone contacts wiped away during the upgrade. I found this tool and safely backed up all of my 260 iPhone contacts to a folder on my PC.
What's more is that after the upgrade the app restored my entire contacts list back to my iPhone in no time. Well done.
