What do you do with it, or what is it used for?
Really....?? I didn't know this..... if I had, I wouldn't have installed it...It's an app that collects all the numbers from friends and family you have on your phone and shares them without permission with facebook and other interested companies to use them for personalized ads and other stuff that noone really knows. In exchange for that you get a little chat functionality.
You have the ability to send pictures and video clips easily, plenty of emoticons and you have an ability to form discussion groups for all kinds of purposes.
But I don't know anyone who doesn't use it.
I guess you're right, Hatayas..... I can't recall which option I chose when signing up....?? I do believe that WhatsApp is free to use as opposed to mainline text messages.... I guess that's the main reason most folks decided to join it, depending on their individual payment plan in regards to the amount of inclusive text messages...?Actually, we had an option not to allow WhatsApp to use our contacts (we were given a heads up)and we used it.
Probably Music, E-mail, and Google Chrome. I'm not really on my phone a lot and I don't have an iphone or facebook, either.
