Prior to iOS 5.1, photos uploaded to Photo Stream in the iCloud are read only and can not be deleted. Apple fixes this annoyance with the release of iOS 5.1. You delete Photo Stream photos in the same manner as you would delete photos in the Camera Roll album:
- To delete a single photo, select the photo by tapping the photo when you are inside Photo Stream album. Then tap on the Trash icon to remove it.
- To delete multiple photos, on the main Photo Stream screen, tap on the action icon. Then tap one after another to select the photos to delete. And then tap on the red color Delete icon to remove the selected photos.
