The thing I've seen at a few weddings recently is that right after the processional, they have a period of like 30 seconds where they allow everyone to take a picture of the couple, then phones away for the rest of the ceremony. I'm sure it's not 100% effective, but it does seem to scratch the itch for most people. I think also by calling such explicit attention to the rule at the beginning of the ceremony, it makes it seem ever more rude to violate it later.
