I have just begun playing around with it and was trying a few things out. I noticed that when I took a photo it would automatically be put into the Photo Stream album and was almost immediately visible within iPhoto's Photo Stream album. The only thing is that I can't seem to find a way to delete the ones I've taken and were automatically put in Photo Stream. I've deleted the original ones from the Camera Roll but they are still showing in the Photo Stream album on both the iPhone 4S & the iPHoto library. Ideas?
