Most LG phones have the ability to accept ringtones in any format so playback is feasible for any ringtone. Online sites like 3gforfree.com and ventones.com are available so you can put ringtones on your phone, from either your computer or the phone itself. Ringtones can also be created and transferred to the phone via USB sync cable or downloaded directly from the Internet to the phone.
Connect the LG phone to your computer. Plug the LG USB sync cable into the phone's jack and the computer's USB port. Watch for a window to appear on your computer to prompt you for action.
Navigate to the LG phone in the window. Click "Open Folder to View Files," and select the "Media" subfolder.
Put the ringtones on the LG phone. In a new window, open the file location of the newly created ringtone file. Highlight the ringtone file, then drag and drop it to the LG phone's Media phone to transfer the ringtone to the phone.
Download ringtones straight from the Internet. This can be done through mobile Internet, and a computer Internet connection. Go to the ringtone website's URL from either your LG phone's mobile Internet, or your computer's Internet browser. (See resources for ringtone downloading websites.) Select the genre of music in which your ringtone falls, whether it be classical, hip hop, rock, etc. Browse through the list of ringtones, and double-click on the one of your choice. Provide your cell phone number when prompted to, and click "Send". The ringtone will come to your phone via text message. Click on the ringtone's link to download and store it to your phone.
