Does Photo Stream automatically erase camera roll?
I've been checking Apple Photo Stream FAQ and still have some fundamental questions:
1. It says iCloud storages your photo stream for 30 days. Then what? Do they gradually disappear from photo stream, from old to new, to give space to new photos?
2. Do those photos disappearing from photo stream ALSO disappear from your camera roll? This is confusing: From there, you can browse your recent photos or move the ones you like to your Camera Roll or another album to keep them on your device forever.
3. Why I still have have very old photos in my photo stream? Aren't they supposed to automatically disappear?
4. If I turn My Photo Stream off in my iphone iCloud settings, it tells me "...will delete all photo stream photos from your iphone". Does this include those that are ALSO in the camera roll — I currently have some photos in both the roll and the stream.
thanks
