Actually I just left the ZTE website and they walked me through how to set ringtones for each contact.. bring up a contact, click the little pencil, scroll all the way down until you see a little bell. it will have 'default' beside it, click on it. from next screen you can choose simple soundfile or change tab to 'music' and anything you added to music from your computer can be chosen for a ringtone for that person. click OK, on next screen click 'Save' your song is saved as that contacts ringer! drove me crazy and I have to say the live chat person had to work for several minutes before he figured it out.. he had never been asked that question before.
