As a iOS app developer I love to use this phone so much. I have remember it was first big screen 4 inch(320X568) phone by Apple after 3.5 inch (320X480) screen which is 3G, 3GS, 4 and 4S. It was the completely new sensation in iOS touch devices. People were crazy about this device and it became the most popular deivce. iPhone 5 is very good in performance and when you start using this phone then you will know the brand value of Apple and you will know why the people are crazy about the Apple devices.
