On Monday, T-Mobile quietly raised the price on their iPhone 5.  

Everyone using T-Mobile had been waiting a long time for the carrier to finally get on board and start selling the iPhone and last month they finally got on board.  

T-Mobile has been losing customers for several years now and the addition of the iPhone was hoped to make a shift in those numbers and increase users.  

T-Mobile boasted selling the base version of the latest iPhone for about $100 upfront with monthly payments of $20 for two years.

The upfront payment for the 16-gigabyte model is now about $150, pushing the total cost of the phone from $580 to $630. At other major carriers, the phone generally costs $650 if bought without carrier support, or $200 with a two-year contract.

T-Mobile also sells a 32-gigabyte model for about $250 upfront and a 64-gigabyte version with a $350 down payment.

T-Mobile sold 500,000 iPhones in the first four weeks it was available

T-Mobile sells the older iPhone 4S with a down payment of about $70 and $20 a month for two years. The iPhone 4 comes with an $18 payment and $15 a month.

T-Mobile was the last major U.S. wireless provider to sell the iPhone, a gap that executives have cited as accelerating the loss of valuable contract customers to competitors. In 2012, it lost more than two million contract subscribers, while Verizon Wireless added more than five million such customers. (via wsj.com)
