Adding "with a voltage regulator" shouldn't be any more legit than "...but on the interwebs!".
It looks to me like a snow job. Putting a camera in a smartphone and then (steady yourself) emailing the pictures you take! Seems pretty thin. So throw in a bunch of the technical details that all electronic devices have in common like voltage regulators, chip enable lines, data busses etc, and a bunch of the mundaneness of networking, like the sizes of email headers etc and now we're looking like we've got something that will sneak past an examiner or impress a layman.
I think the point is that Samsung didn't patent "emailing pictures from a phone", but they did patent a very specific, integrated method of doing so. If somebody (Apple) offered the same function, but implemented it differently than as claimed by Samsung's very specific patent, they would be in the clear.
That's an important distinction that a lot of people are overlooking in this discussion. It's not the end result that is patented, but rather the process or method to achieve that result.
