Since Apple is currently only selling three iPhones, the list is certain: iPhone 5, iPhone 4S, and iPhone 4. The iPhone 5 was ranked first, with the 4S ranked third, and the 4 ranked fourth.
With the introduction if the iPhone 5, the iPhone 4 became free (on contract), and sales 79 percent from Q3 2012. Meanwhile, iPhone 4S sales grew 43 percent when compared quarter-to-quarter (its price dropped, as is natural for the year-old model, to $99 on contract). The iPhone 5 accounted for 43 percent of all iPhone sales in Q4 2012.
In addition, the iPhone 5 accounted for nearly two-thirds of all smartphone sales on post-paid service plans with a value over $200. While Samsung made considerable gains during 2012, rising to 30 percent of all U.S. smartphone sales in Q4 2012, up from 21 percent year-over-year, the bad thing was that the gains were made mostly at the expense of other Android OEMs, such as HTC or Motorola, while Apple’s overall market share remained basically unchanged.
Apple’s holiday quarter, Q4 2012 or fiscal Q1 2013, included sales of 47.8 million iPhones and 22.9 million iPads. However, while it appears those numbers helped to remain the leader in both smartphone and mobile device sales in the U.S. -- as well as becoming the leader in mobile phone sales -- it didn't sit well with analysts and investors, as the numbers fell short of estimates.
