Check Trip Itineraries On Your Mobile with TripIt Mobile

TripIt is announcing the launch of a mobile service today called TripIt Mobile. TripIt aggregates your trip plans into a nice "folder" for each trip which makes taking the actual trip easier. Instead of carrying around printouts of your travel plans, TripIt can bundle it together and now deliver it directly to your mobile for later retrieval.

The company also noted that the mobile version is great for their "closeness alerts". These alerts tell you when someone on your TripIt friends list is near where you will be near. I wrote about these alerts before and had concerns about the privacy of my trips. Check out the explanation for more details.

I am still looking forward to seeing how this company plans to generate revenue since their service is free. They have a travel search which I am assuming they make a rev share on but isn't TripIt an "after the purchase" service?
