T-Mobile has announced its earnings for the 2011 holiday quarter, and the GSM carrier lost over 800,000 subscribers. Being the only major U.S. carrier left not carrying the iPhone, T-Mobile saw a 3.3% decrease in revenue to $20.6 billion.
Although the network’s growth has been on the decline for awhile, the fourth quarter of 2011 resulted in an exponentially greater loss following the launch of the iPhone 4S.
