Sprint Nextel legally joined the growing chorus of objections to AT&T's plans to acquire T-Mobile today when it filed a lawsuit in U.S. District Court in Washington, D.C.

The company, which is the third largest wireless carrier in the United States, reiterated its concerns over the deal, primarily that it would push the wireless industry toward a duopoly controlled by AT&T and Verizon, limiting innovation and consumer choice. The proposed merger, which the lawsuit calls "brazenly anticompetitive" would make life harder for smaller carriers like Sprint, who would be in less of a position to competitively challenge the two dominant players.

Earlier today T-Mobile officially launched the G2, its successor to the the company's flagship Android-powered G1 handset. In its announcement, T-Mobile's top selling point wasn't for the phone's hardware but for the fact that it can reach "4G speeds."

That little twist of language (is it 4G or isn't it?) comes on the heels of AT&T chiding T-Mobile earlier this year after T-Mobile called its own network 4G when in fact it's a revamped kind of 3G. Big carriers having a spat over marketing language? Or genuine disagreement over what those networks really are?

Here in the U.S., your choices in phones running Google's new Android operating system have been limited. If you weren't a fan of the T-Mobile G1 form factor - a design best for heavy texters thanks to its slide-out keyboard - you were pretty much out of luck. No more. Word has it that Samsung will soon be releasing their own Android smartphone for use on both the T-Mobile and Sprint carriers.
