Before installing any app from the app store, you have to put apple id which is very annoying.
As according to me, you shouldnt buy it but still if you want you can give it a try, and now a days as we can see, iphone 7 is going to com, it doesnt have good resale value.
So, you should buy a android phones istead of buying iphone 4 in this price.
Thankyou for reading.
