You can't email ringers to your phone...we have all pretty much tried at one point or another
A lot of people go to a free hosting place...and host them there. Some of the people here upload them to their own servers.
I can provide some server space for you to upload your ringtones to.
All you have to do is go to where you have them hosted and click on them to open them, when it opens use the trackwheel to go to the save option.
So if your interested in borrowing some server space from me for a bit let me know (that goes for anyone here on the forum)
