Before the update, photos saved to camera roll would automatically go to photostream, too. You could then delete them from camera roll but they would remain on your photostream.
Now, you can still add photos just like you could, but as soon as you delete them from your camera roll, they are also simultaneously deleted from your photostream.
Any help on how to keep your deleted camera roll photos on your photostream?
A photo stored in the Camera Roll is permanently stored on your device (until you delete it). Only 1,000 photos are saved in the Photo Stream on an iOS device, so if enough photos are uploaded to your Photo Stream the old ones will be purged. (But a Mac or PC will save all of the photos in your Photo Stream by default.)
According to Apple, the downscaling does only apply on iOS devices — if you have Photo Stream set up on your computer, those photos will be full-resolution.
On your Mac or PC, your photos are downloaded and stored in full resolution. On your iPhone, iPad, iPod touch, and Apple TV, your Photo Stream photos are delivered in a device-optimized resolution that speeds downloads and saves storage space.
Yes — to delete multiple photos, just tap the action button in the upper right corner, select some photos, and tap the Delete button.
Yes, iPhoto says there are duplicates because of the photo stream. But there IS a button to erase all remaining (not sychronized because of duplicates) photos from the iPhone directly within iPhoto after you did an import:
That does not solve your desire for an elegant wireless way. I simply think it's not possible to delete all photos at once directly from the iPhone (with built-in apps). Of course you could delete them by marking them one by one in the Photo apps using the "Edit"-Button.

Apple apparently didn't realise just how many photos people were going to want to keep online, so they've dramatically reduced the retention.
If you want to keep photos, don't keep them on iCloud, keep them on your computer.
