Apple also said it sold a record 26 million iPads in the quarter, compared with 22.9 million in the year-ago period …

Foxconn – the informal name for Hon Hai Precision Industry – is responsible for the bulk of Apple’s iPhone and iPad production, with secondary supplier Pegatron leading production of the iPhone 5c and iPad mini.

Apple reported record revenue of $57.6B for its fiscal Q1 2014 (calendar Q4 2013), with record sales of 51 million iPhones and 26 million iPads, alongside 6 million iPods and 4.8 million Macs.
