If you're bob.blog, you just email the document to your iPhone, and voila-- the groom reads his vows right off of the gadget of the year for 2007. Pretty darn nifty. No word, however, on if the bride sent her "I do" via SMS.
Now, it's not the first time an iPhone has made a wedding possible, but it is, from what we can tell, the very first actual iPhone-assisted wedding ceremony (Update: Not true-- see below). Just think what we'll be able to do with wedding software when the SDK hits. With this ringtone, iTheeWed!
Update: It's not the first time this has happened-- TUAW's own Mike Rose tells me that he can personally attest to this having been done before. He attended a wedding where the groom read his vows right off of the iPhone. Looks like a burgeoning market of vow-reading software to me.
