Apple iphone 4s is an amazing phone with special features. It has ios operating system.It is screen size of 4 inches and very easy to hold.It has both back and front camera.The phone is very strong and has very less chances of breakage because it has been prepared with strong material. The another thing which I like about this phone is that it has an excellent sound system which you will not find in any other phone, thats why "apple is apple". The phone never hangs like other phones.The cost of this phone is 13, 000 and very affordable.
