A new service from Myxer allows users to turn any song into a ringtone for their smartphone or cell phone—all for the cost of a text message.

Called MyxerTones, the service asks you to choose a track from your computer to upload to Myxer's server and enter your cell phone number. Once the file is uploaded, it SMSs you a link to where the new tone can be downloaded.

You must have Internet access with your smartphone to make this work.

I just tried Myxer. It took about 20 seconds for the audio file to upload and less than five seconds for me to receive the text message with the link to my new ringtone.

Next, I tapped the link in the text message to download the tone. MyxerTones attempts to figure out what ringtone format would work best for your particular handset. If it can't, the service offers a dropdown menu to allow you to download your tone as either an MP3, AAC, MMF, QCP, AWB, AMR or WAV file — one of which should work with your device.

To know for sure, I recommend you check the documentation that came with your handset.
