Just got a new iphone. I use TMobile services. How do I get a ringtone from itunes? Is there a way to make my existing songs into ringtones? I even tried to buy a new song that said it had a ringtone, but I paid 99 cents for the song and then 99 cents again for the ring tone? I am not technical at all--but I can get my husband to help me if I can follow some easy directions. Thanks!
