My computer was stolen that had my backups to my iphone. Now I have my iphone with all my info (contacts, pictures, settings etc...). My other computer has never been tethered to this iphone. I need to connect it to itunes to unlock it. Will my phone be wiped if I tether to an itunes/cpu that it has never been tethered to or will i retain my contacts, apps, etc..? Just want to make sure i do this right.
