Along with Fb plug in some other apps which are really useful to chat or stay connected with the world (provided you want to ;)) are Whats-app, Talkatone using which you can chat with friends over gmail yahoo etc . Below are some of the images of my Iphone showing some interesting and some fun apps I use!
This article would be incomplete if I don’t mention the Facetime/ Facedial.
It’s a free video chat service provided for apple users ofcourse! You can facetime each other and its pretty clear and better than a phone call . For others there is ofcourse a skype app which is a cooler one too!
