Find a Cruise, or an Embarkation Port on Your iPhone

As a rule, I'm not one to promote products that I don't own or have at least tried out. However, I'm not about to give up my trusty BlackBerry for an iPhone, so this is something I can't share first-hand experience with. The ability to view deck plans on a small screen is probably better left to people with keener eyesight than mine, but I do like the idea of having port directions at hand
