Time to throw some rice and get ready to catch the bouquet, because the marriage of T-Mobile and MetroPCS is now complete. T-Mobile announced this morning that the two companies are now one and that the combined entity, known as "T-Mobile US," will begin trading on the New York Stock Exchange as "TMUS."

The new-look T-Mobile has a subscriber base of approximately 43 million customers and a board of directors that consists of 11 members that are a mixture of T-Mo and MetroPCS executives. John Legere, who served as CEO of the old T-Mobile, will head up the new T-Mobile US as President and CEO, while former MetroPCS CFO J. Braxton Carter will be T-Mo US's new CFO. It's also worth noting that, despite the fact that T-Mobile and MetroPCS are now one big company, they'll still be operated as two separate brands.

On the network side of things, T-Mobile US says that there are 301 million people covered by the its combined network. There are 228 million people that have access to 4G HSPA+ service, and T-Mobile expects to cover 200 million people with its 4G LTE network by the end of 2013. The company expects its LTE network to continue to grow and improve as it combines the T-Mobile and MetroPCS's spectrum resources. In 2014 and beyond, T-Mobile says that it plans to have have at least 20x20MHz of LTE service in around 90 percent of the top 25 U.S. metro areas.

Considering that T-Mobile US will continue to operate its T-Mobile and MetroPCS brands as separate entities, it doesn't appear that customers will notice any major changes right out of the gate. However, T-Mo and MetroPCS have previously said that they plan to repurpose Metro's CDMA network into HSPA+ and LTE service, meaning that Metro customers will eventually need to pick up a new GSM device. Exactly when that time will come remains to be seen, but I'm sure that T-Mobile US will give its subscribers a proper heads-up before the change actually goes down.
