Are all those addresses already in your contacts list? I don't know any way to do this on the phone, but I'd think it would be faster and easier to just do it with Google on your computer instead.
There may be an app that lets you import waypoints/points of interest for the iPhone, but that seems like a long shot for that many points.
You can just enter them in the Directions tab on Maps, and it has a memory to store them, just like Google Maps.

You need a GPS app, CoPilot, Navigon, TomTom, Sygic, all have multiple route points.
And no you still can't drop multiple pins in the Maps app, which is really annoying since you cannot for example measure distance between two locations(say Dublin - London), unless your current location is one of those locations.
Sorry, yes you're right.Are you sure about your second point? I just mapped that (Dublin - London) even though I'm in San Francisco. You can press on 'current location' to get the circle with the "x" to remove current location and enter a location of your choice, a contact, a bookmark, or your current location again.
Regarding the subject of the thread, I tried multiple locations using mapQuest's app, but didn't like it because the map isn't as smooth as the stock app and the location markers don't name the contact or location (retailer, museum name, etc.) even if that location is a contact.
Multiple pins in Maps would be so much better.
ANSWERED:
There is an app called Maps+ (red icon with a compass symbol) that allows you to drop and save multiple pins at the same time. You can also make alarm pins for when you enter or exit a certain radius. Sweet app.
