Ringtones and sounds are one of the most important aspects of any mobile phone. Having a custom ringtone for each contact would be great fun as you can identify the caller without even having to see the phone, if the ringtone is unique for a caller. You can assign different sounds to different kinds of alerts and different ringtones to different people.

To change a ringtone for a contact;

• From Start, press People, then flick to All.
• Press the contact for whom you want to change the ringtone or set a custom tone.
• Now Press Edit.
• Now Press Ringtone.
• Choose the ringtone you want to assign from the list and then press Save.

Now if the contact calls you, you can see the ringtone in action.
