This is for iphone replacement policy. I had purchased Iphone4 8gb in Aug-13 but in Feb I faced some issue in my iphone. So I visited in Pune authorize center(RSG info-tech) and they told me that they will repair the cell.
After that, they will decided that this entire phone will be replaced or not and it will take around 7 working days,
But as per my knowledge, Apple will replace the phone if hardware issue is found regarding this I also communicated with Apple customer care in India. But they told that they have changed this replacement policy in Dec-13 and that the entire phone will not be replaced. but they will try to repair first and that rules will also applicable who purchase this phone before Dec-13.
So I really think whats the meaning of purchasing an iphone? Other good mobile phones are there in the market.
