If you're a Sprint or T-Mobile customer there's an interesting new rumor coming from The Wall Street Journal today that might be of concern you. According to people familiar with the matter, Sprint is reportedly preparing a bid to purchase T-Mobile in the first half of 2014.

Sprint is studying regulatory concerns and could launch a bid in the first half of next year, the people said. A deal could be worth more than $20 billion, depending on the size of any stake in T-Mobile that Sprint tries to buy.

It’s noted that at this point, Sprint hasn't yet decided whether to move ahead with a bid but if they did, that would bring the third and fourth largest U.S. carriers together in an effort to take on the likes of AT&T and Verizon Wireless.

Assuming a bid is placed, it's highly expected to face criticism from antitrust officials and the the Justice Department who only two years ago denied AT&T's offer of $39 billion offer to buy T-Mobile.
