Send location data in photos

Does anyone know if it is possible to send the location data from photos taken on one iPhone to another?

Basically, to explain my situation, I went to a party last night, and one of my friends took a bunch of photos on her iPhone. This morning she bumped them to me, but the location data did not come with the photos. I didn't ask her, but perhaps she didn't have location services on at the time (I highly doubt this though). Haha, am I just asking a useless question?
