How do you delete a "Camera Roll"?
When I first set up this phone, I downloaded my iPhoto pics from the desktop iMac from iPhoto. It created a folder called Photo Library. All new pics taken on the iPhone are in a separate folder called Camera Roll. Everything in Camera Roll is separately editable and can be deleted. The entire Photo Library can be opened and photos selected, but there is no way to delete them, either individually or as an entire set.
In iTunes, all the iPhoto library this folder cam from is shown de-selected, so following the support instruction does not work. It wants to add them again if I choose any. How in "heck" can this folder be deleted? It uses more than half my available memory?
