I'm wondering if there is an easy way to sync/share all of my photos, current and future, between my iPhone and my iPad. I know I can share my photo stream...but that appears to only share all future photos I take. I know I can "beam" photos between devices, but that only puts "hard", individual copies on each device. What if I edit a photo on one of the devices? It'd be nice to have them synced. I'd like to take all of my current photos from my iPhone and sync them with my new iPad. If I edit one of those photos on either device, they sync the updated files between each device. And if I take any new pictures with either device, those photos get synced as well. Is there some sort of simple solution I'm missing here?
