I was using the iOS7 beta for a week and decided that it was not for me. So i downloaded the 6.1.4. ipsw file to restore my phone. However, like an idiot, i backed up my phone on iTunes on my mac with iOS 7 installed. When 6.1.4 finished recovery it was a brand new OS with just my contacts on there and pictures I had saved from iPhoto however no pictures from the camera roll that I had prior to my iOS7 installation backup. Is there anyway I can some how recover the pictures I did not sync to iPhoto which were on the backup file I had on 7.0?
