How do I transfer the ringtones to my sprint Lg Touch?

Hi,

There are different ways to connect to and and transfer data to a cell phone. You would probably want to opt for the data cable here in order to get the ringtone files you have created (probably MP3s) onto the phone. So, hook up the phone via your data cable and also have a look at the documentation for more details as to how to instate the new ringtones on your phone.
