How to set the ringtone of G 10 mobile phone, I don't understand.

1. Press menu-voice-incoming call (ringtone)-select the ringtone you want/or press new ringtone-select music tracks-OK-and then find the new ringtone you just added in the list below-and the application will be OK.

2. Or drag it to the bottom of the personalization in the lower right corner of the screen, and there will be a ringtone-the same as the first step.
