T-Mobile gets iPhone 5, 4G LTE, Samsung Galaxy S IV

T-Mobile USA announced Tuesday that it would drop two-year contracts, roll out 4G LTE and get two of the hottest smartphones on the market.

The mobile carrier said it will get the iPhone 5 and Samsung Galaxy S IV.

T-Mobile will start offering the iPhone 5 on April 12. The company is currently the only major U.S. carrier not to offer Apple's popular smartphone. At an event in New York on Tuesday, CEO John Legere said the lack of an iPhone "was such a huge void in our device portfolio."

T-Mobile also announced that it was getting rid of its two-year contract, making it the first major wireless company to give customers an option to switch carriers without penalty.

T-Mobile is charging $100 up front, then another $20 per month for two years, on top of the service fees for voice, text and data that start at $50 per month - cheaper than others. Customers could leave T-Mobile during that time, but would still have to pay the installments.

The wireless network has, until recently, not been able to offer high-speed data service to iPhones. It's now able to offer high-speed data to iPhones in some cities.

Samsung's Galaxy S IV is also coming to T-Mobile on May 1. There are currently no details on what how much the smartphone will cost.

T-Mobile also announced that it will launch its own 4G LTE network. The service will roll out to a handful of cities, including: Baltimore, Houston, Kansas City, Las Vegas, Phoenix, San Jose, Calif. and Washington, D.C.
