CallTell is the next advancement in iPhone communications. Find out who's calling you BEFORE looking at your phone! CallTell announces who's calling you before ringing. It also works for text messages! You can even have CallTell read the text message out loud as well. You can enable/disable certain features via the CallTell page, in the Settings app.
This takes its volume from the mediaplayer volume, so turn up iPod volume if you are having issues
