I bought my first Apple phone a year ago and it was a black color, shining iPhone 4S, 64Gb version. Till date I’m happy with it. It is one of the best phone I’ve ever used in my life.
Camera: The picture quality is very crisp and awesome. It has a 8MP rear and front is VGA. Also, the inbuilt filters are pretty amazing. Personally, I like "Chrome" filter.
Memory: As I have bought a 64 Gb phone, Memory is never going to be an issue for me.
Platform: It comes with iOS 5 when bought but it can be upgraded to the latest iOS on which iphone 6 is also running that is iOS 10.1. The iOS is one of a kind, easily accessible features, It also has a cortex A9 processor which doesnot have any lag and runs smoothly.
Sound: It has a very clear and crisp sound. Loudspeakers have pretty good sound and music can be heard inside the entire room very easily.
The only cons are the:
Battery: it drains very fast on Wifi as well as on 3G. It has a very low capacity of only 1500mAh.
Bluetooth: No bluetooth FTP possible. Only you can connect hearing devices and speakers.
iTunes: Specifically, iTunes is required to transfer data.
I would say that its value for money. Every penny spent on it is worth.
