Combining all of your contacts into one, integrated & searchable list, fring indicates who's online (presence status) and available before dialing. All you need to use fring is a 3G handset with Internet connectivity that is already available from your mobile service provider or through your nearest Wi-Fi hotspot. fring is PC-independent, does not require any proprietary hardware or airtime, and works with phones purchased through any mobile operator. fring is as easy to download as a ringtone.
