Even though you have Voice Memo on your iPhone you might also be interested in the free Pocket Dictate, which lets you make recordings and then tap the send button to e-mail it to your typist from within the app. You can also send it via ftp. The app automatically compresses the WAV file. There are other useful controls, too, including the ability to overwrite and insert. A voice activation feature lets you set it so that it only records when you're speaking. And while it's designed to emulate — and replace — a dictaphone, obviously it could be used for other purposes, such as interviews.
