Remember, you MUST run the app first on your device in order to register!
NO App or Developer has access to your email unless you willingly provide it, which is a good thing if you think about it!
Run the app (100sounds, 100birds, or 100animals) on your iPhone.
Touch the (i) button in the top right of the app to get to the INFO page.
Press the BIG rectangular button that mentions ringtones and our web site.
Enter your email, make sure the box is checked, and touch REGISTER.
Once registered, you can either use the iPhone to have groups of ringtones (ZIP files of 5MB or less) emailed to you, or use this form to select ringtones to download.
Use whichever method you find easier.
