PhotoStamp "stamps" any image stored on your iPhone with a copyright line, URL to your Web site, your name, or any custom line of text, and then saves a copy of that image in your Camera Roll. Options include a custom stored text line, a button to make it easy to include a copyright symbol, and black or white text.
Thanks for the great suggestions! Im working on font sizing and color, position next, and just starting to look at updating the EXIF data.
