The release of the iPhone 4s was thought to be a let down when everyone was expecting it was the iPhone 5. However, the iPhone has been a total success where in October 2011 accounted for 90% off all phones being sold in the United States. Out of the iPhone’s been sold, 89% was attributed to the iPhone 4s, 7% to the iPhone 4 and 4% for the iPhone 3GS.
The iPhone hype gets stronger when a survey conducted by the All Things D, found that 43% of customers on a contract actually broke it, in order to get their hands on the device.
“An amazing 19 percent of all iPhone buyers upgraded from the iPhone 4, a phone barely a year old at the time of the launch,” said CIRP co-founder Mike Levin. “Forty-two percent of iPhone buyers broke existing carrier contracts to get the new iPhone 4S. And 19 percent of these iPhone 4S buyers sold their old iPhone in the secondary market. Early upgrades, broken contracts, and selling used phones — all allow buyers to purchase the new iPhone 4S, when conventional wisdom suggests that these users would follow the two-year contract cycle, or at least purchase the cheaper models.”
