Restoring backup
Yesterday I went to the Apple store to get my iPhone fixed. They determined that it needed to be replace because of hardware problems (which I still needed to pay for) and that I should backup my phone. I backed it up on my iTunes, it took a good hour. Now, today, I'm trying to restore my phone and it wont allow me to restore it because it says my passwords wrong. The same password I used yesterday at the Apple store, that worked! So i go into iCloud and my passwords fine. I go to Apple Inc. use my Apple ID and current password and it worked! I even signout and sign back in to iTunes and it worked, but at the restore button my password does not work. Determined I decide lets log out of everything and try reseting the password. After going through the process it still will not allow be to restore my iPhone. Please Help!! I've had no phone for two days, its frustrating, and limiting my ability to connect to my job.
Thanks
