Hi. I have been a faithful buyer, when it comes to Apple. I know that the 4th generation of iPhone has been launched in the market and I want to go for it too. Just wanted to do some pre-buying survey of this 4th generation. How much is it different from its previous versions? What are the coolest features that it offers and how is the iphone 4th generation as a iPhone? Can you give all this info to me as soon as possible? Have a beautiful time ahead guys!
