GPSModifier (was Photo GPS Exif Editor) lets you view, add, change or delete location/GPS information in your photos.
If your camera can't save location information in your photos, don't worry. You can use this app to add a location to your photos so you know in 10 years exactly where you took the photo. Even if your camera has a GPS module, the location might not be accurate enough in some photos. Sometimes you know better where you took a picture. You can change it. You might want to delete location information stored in your photos. That's also possible.
