I am already using iphone 5s . Its is more comfortable for me. The camara clarity is very good. Very important not hang like other phones work very smoothly.
The customer support is very good .once I was forget my I clouds password and my phone was locked . I call the customer care they help me to unlock my iphone .
One feature I most like find my iPhone. With that my phone's data is secure. If I lost my phone nobody can see my personal data .
