UIQ

Well, i know that ringtone is not a theme of UIQ but it looks pretty interesting, is a ringtone unaudible for adults.

When people ages, they lose a little bit their hear sense, so they can’t hear some sounds in low frequences, well, there’s a ringtone that adults can’t hear, it’s ideal for school or something like that. Try it.

P.D.: Don’t think that i don’t have more UIQ applications, next time i going to post a SMS Spam Blocker for our phones.
