Since itunes wasnt working properly on my system, I backed up a camera roll of my iPhone 4S onto my laptop using iTools. After resetting my iPhone, I synched the backed-up camera roll with the iPhone from the laptop. The backed up folders were overwritten after a little while by a new photos folder so I lost all those pictures. I had deleted the backup from my laptop too. Is there any way I can get that backup back on my iphone?
