Even if all of these customers kept their iPhones locked to these carriers, this number would leave around 1.3 million iPhones unaccounted for—approximately 35% of total iPhone sales in 2007. Although it is possible that a large number of customers who received the devices over the holidays might not have activated them by the end of the year, the number would not likely push the overall percentage below 33%, or one-third of all iPhones sold during the year. In addition, not all iPhones sold in Europe were sold locked, as both Orange in France and T-Mobile in Germany offered unlocked versions of the phone, albeit at much higher prices than their locked counterparts. It is presently unknown as to how many of the officially unlocked phones were sold.
To date, Apple has been unable to supply a concrete metric on how many handsets were being sold with intent to unlock. However, Apple Chief Operating Officer Tim Cook, speaking during the company’s Q1 Financial Results Conference Call, said that the company believed the number to be “significant.”
