i think i figured it out. on the page of the ringtone you want, below the track you will see download: mp3, etc...choose whichever type of file you want but RIGHT CLICK it. click "save target as.." and save it on your desktop. then open your email and create a new message, with it as an attatchment, nothing in the body or subject. and the address you send it to depends on your number and carrier. for instance, mine was tmobile, and lets say my number is "(757)000-1111" i would email is to firstname.lastname@example.org or if my carrier was verizon, it would be email@example.com hope it helped!
tried that 3 times when did u actually get it cuz i've been sitting here 4 3 hours
