Okay, I need a little help. So I needed to get my iPhone 5 replaced today in the Apple Store, but since I had iOS7, i had to put it back to iOS6. Before I did a DFU Restore in the Store, the employee asked me did I backup everything first, and I said yes. Okay, I got my phone replaced and came back home to my computer to put all my photos back on. Thing is, there are NO PHOTOS OR VIDEOS from July 27th to Today's Date. I constantly backup, to my computer and iCloud. Is there a way having iOS7 could have deleted my backed up photos on my computer? Please guys, I really need some help. There are a lot of special pictures on there and I really want them back.
