Hi. I'm currently using a 16GB iPhone 4S. Unfortunately 16GB is not enough for my needs anymore and I decided to delete some unnecessary things. One of those are the images on it: I rarely look at the pictures on the iPhone, having them synced to iPhoto using photostream is enough for me. So I made sure all pictures were saved on my mac and disabled photo syncing in iTunes. But after this and deleting the existing pictures through iPhoto there still are plenty of pictures left. Can anybody tell me how to get rid of those?
