According to one analyst, Apple could sell as many as 46.5 million iPhone units in the quarter ending on December 31.
Despite Foxconn recently admitting that the iPhone 5 faces production delays, Sterne Agee analyst Shaw Wu said supply chain sources have said that the firm has been able to increase its manufacturing capacity for the smartphone.
Wu told investors that should production stay on track, Apple can replenish stocks on time and sell tens of millions of iPhones.
If Apple manages to sell 46.5 million iPhones, it would represent a considerable leap of over 50 per cent year-on-year growth, which was 26.9 million sales during the final quarter of 2011.
Apple has sold over 125 million iPhone units in 2012 thus far, with the first quarter attributing to 37 million sales.
