How many iPhones can I bring to India? [duplicate]

I have a confusion regarding the number of phones i can carry with me . As the iphone is cheaper in usa compared to india i wish to carry many iphone's with me (what is the max limit) .

I also do not want to pay the import charges , let's suppose if i unpack the phone's and the earphone's from the box and carry it with me. will tell the officials that they are all mine will they allow me or not .

edit 1. - i dont plan to sell these phones , i'll give one to my wife and rest will be used by me as official phone , personal phone and backup phone

edit 2. - i know there are other question on this same topic but they dont answer what precisely i wanna know i.e. if i just keep all the phone without any packing and that too in seperate baggage (2 phones in 2 seperate luggage bags , 1 in my pocket and the last one in my hand bag ) will it still rightfully attract custom duty .
