Fring, a social voice chat software similar to skype, has just been
released for Android. The software will not restrict the use of wifi
for the data network, so you will be able to use wifi with Fring instead
of carrier data if you choose. Fring will work on 3G, 4G, and WIFI.
The software will offer international rates starting at $0.01 per minute
to select locations. The application can be downloaded for free via the
Android Market Place.
