I've tried a search but haven't found what I need. My sister just bought a D2 and wants to set the ringtone for certain contacts to "silence"... I have a DX and I don't seem to have a selectable ringtone that is basically "no ring" or "silence". How would she accomplish this? On my DX I can select music or android ringtones... so I guess if I could record silence as a song and then select that for my ringtone that is one way around it... but I'm relatively new to the Android system and my sister is extremely new to it... and lives in another city so I'd have to figure out how to walk her through it over the phone!!! Would be nice if her D2 allowed her to simply select a silent ringtone (or no ringtone) on a contact by contact basis. thoughts?
