The plug for the charger to my iphone 5S stopped allowing it to charge. It was under warranty and Apple replaced my phone with another. The "new" 5S will not allow the backup that I have saved to my Windows 7 computer to be restored to this new 5S; I could only restore that which was on the cloud...no contacts, which are what I'm most interested in recovering. The "Wondershare Dr. Fone for iOS" download indicates that it can help me recover those contacts but I'm hoping someone might be familiar with it. I certainly don't want to download something nasty to my computer. Thank you for any help.
