I ran across this page this morning from The Support Group documenting how to get your iOS geolocation data into a FileMaker Go database on a supported iOS device (the iPhone and the wifi+3G models use Assisted GPS). This can simplify point documentation for those who work on more regional projects. You have to register for the database file but the resulting file is unlocked so you can see how it works.
While not as versatile as Filemaker Pro, Bento 4 was released this morning and allows collection of location data in both the desktop and the updated iOS versions:
