Sharing Large .wav Files From iPhones
 

I have people around the country doing interviews on their iphones using iTalk. The files are in .wav format and are 100-175MB in size.
I'm trying to determine the easiest way for them to send the files to me.

Currently, I'm having them connect to their computer, pull the file out of iTalk using iTunes, then move the file into DropBox and sharing with me via DropBox link.

Anyone have any ideas on whether I could be doing this more efficiently?
