Two years after T-Mobile and Sprint announced their merger...

and intense scrutiny on Capitol Hill from lawmakers worried the combination would drive wireless prices higher...

America's No. 3 and 4 wireless carriers on Wednesday finally officially completed their $23 billion merger.

The combined company will now operate under the T-Mobile name and trade on the Nasdaq under the symbol TMUS.

The never-camera-shy CEO of T-Mobile John Legere is stepping down effective immediately. He was originally scheduled to leave at the end of the month.

The deal closed after a Federal judge on Wednesday signed off on the Justice Department's okay of the merger, including the order to sell assets to Dish Network.

And T-Mobile and Sprint went ahead and agreed to abide by any conditions set forth by a final decision from the California Public Utilities Commission, that will come out on April 16th.

The marriage creates a stronger competitor to AT&T and Verizon in the race to roll out 5G wireless technology.

Shares of the new T-Mobile managed to hold a gain Wednesday amid a general stock market slump.
