iphone 4s has failed in the Indian market with its high price and strange issues in the battery and antenna. especially the iphone 4s was popular for the SIRI feature in it, but subsequently there were some issues pertaining to hang the device.
People updated their iphone 4 into IOS 5 and got the SIRI feature and so the 4s demand also saw a great dip.
iphone 4s sales saw a black sales effect because of the high price that would rather make people to afford 2 smartphones or either a laptop even.

That may be the reason for a HOT market for iPhone4 in India. Apple also faces tight competition from its competitors. A high price gadget would be exclusive but this one is not a luxury until the said issues are resolved. Once such issues get involved with a rising product, the trust of consumer gets affected. Currently people are buying iPhone 4, as iOS 5 is available in the for download, like anything as the phone is priced in range and the features are also in line.
