Ringtone Tutorial:
1. Record a 15-30 second audio clip in an audio recording software program such as Audacity. If its a protected M4A file or for some reason it doesn't import, set your program to record from Wave Out Mix, or Mono Out depending on your computer capabilities and sound quality desired (in Audacity, select from the dropdown menu at the top left). This means it will record whatever sound the computer is playing at the moment, and there is no loss in sound quality or anything because it's just recording 1's and 0's basically.
2. Add a 1.5 second fade out effect to the end (In Audacity, highlight>effects>fade out).
3. Export as an MP3.
4. Find out your phone number's email (its commonplace to be able to SMS text email addresses and receive from email addresses. Just go to your carrier's site, go to help, and type in "email my phone" or something similar. For instance, it should say something like <phone number>@tmomail.com for T-Mobile users).
5. Email in plain text, and attach your audio clip to the message. You'll be charged with a picture message fee.
6. You should receive the message, probably an eon later. Hit options or however your phone works, and save the audio, then select it as a ringer. Perfect real-tone ringers. The sound quality really rocks. Beats the hell out of spending $4.00 for a fucking 15 second hi-fi ringer, or buying a computer shit kit for $40 or something?
Edit: My phone drops attachments longer than 20 seconds, so if this is case obviously shorten it
