Viber...

We've arranged a civilization in which most crucial elements profoundly depend on science and technology....Knowledge is of no value unless you put it into practice....

It's called Viber and it is one very cool app for IPhone and Android users. It lets you make free phone calls and send text messages to anyone who also has the application.

I have it and so does my sisters and we have been testing it out with each other and it works just great.  You can call or text an Viber user, anywhere in the world, for free.  Viber integrates with your existing address book, has great sound and quality and once activated, it does not require a PIN, username or any additional application purchase.  All Viber features are 100% FREE!

Free international calls and text messages to other Viber users using 3G or 

Wi-Fi. 

What do you have to lose?   As someone said,  "The  stone age was marked by man's clever use of crude tools; the information age, to date, has been marked by man's crude use of clever tools." 
Not having the information you need when you need it leaves you wanting. Not knowing where to look for that information leaves you powerless. 

In a society where information is king, none of us can afford that...
