Rockifone’s Easy Recorder (App Store link) is a free iPhone audio recorder. Easy Recorder lets you record audio at three quality levels and is a no brainer to record with.

To sync recordings, Easy Recorder has a built-in Web server that runs over WiFi. This isn’t an elegant solution, but it works fine.
