T-Mobile plans to spend $4 billion to upgrade its wireless network to LTE. The failed plan to merge with AT&T has affected T-Mobile because plans to upgrade its network were put on hold. As a result T-Mobile will be 2 years behind Verizon in upgrading to LTE and will be the last wireless network upgrading. Contract customers declined in the 4th quarter of 2011 by 802,000 with all the uncertainty surrounding the merger. AT&T made a cash payment to T-Mobile of 2.3 billion euros for the failed merger. However the situation has turned out negatively for Deutsche Telekom because of a 2.3 billion writedown in the value of T-Mobile USA ,and an additional 800 million euro writedown in Europe. If T-Mobile decides to offer the Apple iPhone to attract contract customers additional financial commitments will have to be made.
