That is a great question, and I am so glad to hear that you like your T-Mobile MyTouch 4G because it really is a great phone. Let’s try this and see if it helps:
- Go to your applications
- Go to your music
- Play the song you want to set as a ringtone
- Press the menu button
- Select more
- Select set as ringtone
- Trim the ringtone
Note: These instructions may differ from the phone options.
Thank you for contacting T-Force,
From what I have heard you need to play the song you wish to edit and follow the instructions above.
If you are having trouble following those instructions or cannot find the option to use the trimmer. Try downloading an application from the Android Market (like Ringdroid). T-Mobile does not support any applications, but I have heard that this is a good trimmer application.
