I just tried myxer. I have used various tools to create ring-tones for my cell but myxer is extremely easy way to create a Ring tone for your cell and have it delivered to your cell phone. Totally FREE.
You can upload any music file from your PC to myxer. It let’s you select the start point and the duration from the music clip that you uploaded. You can listen to the ring tone and adjust or remix other music in the clip. Then myxer simply send a link to your ring-tone to your cell phone as a text message. You click on the text message and download your ring-tone from myxer web site.
You don’t need any wires, blue tooth etc to connect your phone to your PC. Myxer is totally free and you can also select other ring-tones that are already there. Best part, you don’t even need to create an account to use myxer.
