In just three years, Apple’s iPhone has cornered a huge chunk of the smartphone market, and it continues to gain momentum at a rapid pace. But while the iPhone has been a boon to Apple, it’s been just as important to its exclusive carrier partner, AT&T. No other carrier has the iPhone, and this has created a stir among users unhappy with AT&T’s service while simultaneously being a major reason users switch from other mobile networks . The U.S. Department of Justice may not be happy with this and other exclusivity arrangements, though, and has opened a review of AT&T, Verizon, and some of the other major telecoms. According to a report in The Wall Street Journal , this “initial review” will explore issues like anti-competitive practices, the sheer market share of AT&T and Verizon (60% of wireless customers), and the practice of locking up phones via exclusivity agreements.
