With the box.net table below, you can select any of the ringtones I have created to download. Once you've downloaded them, simply open your iTunes and drag the files into iTunes. iTunes will automatically recognize the files as .m4r, which is the file type that means "Ringtone" for an iPhone.... and they will appear in your Tones section of iTunes. When you connect your iPhone to iTunes, select your iPhone from the column on the left side in your iTunes window, then click on the "Ringtones" tab from the top in the middle of your iTunes window... then select which Ringtones you would like to sync, or simply just click "select all". I hope you enjoy them!
(It's much easier to see what these files names are if you select the "Menu" in the top right corner of the box, and choose "list view")
If there are other songs or sounds you would like as a ringtones, feel free to leave a comment on my blog requesting it!
