A resurgent T-Mobile underpinned by aggressive pricing and a boisterous CEO, a new Sprint backed by hyper-fast data and a Japanese telecom giant, and the duopoly — ATT and Verizon — up to its usual antics: just when it seemed like wed finally reached some semblance of stability in the US wireless market, we hear the news from a Wall Street Journal report that Sprint may be ramping up to make a bid for T-Mobile. The network, owned by German telco Deutsche Telekom, is still coming down from the aftermath of ATTs bid to buy it in 2011 for some $39 billion — a bid that failed in spectacular fashion at the hands of the Julius Genachowski-led FCC and the Department of Justice. At the deals announcement, ATT filed a preposterous list of claims about T-Mobiles impotence and irrelevance as an independent entity, saying it had no clear path to launch LTE service and didnt offer a particularly compelling portfolio of smartphone offerings. Of course, two and a half years later T-Mobile now offers LTE and sells flagship devices like the iPhone 5S, Galaxy S4, Nexus 5, and Moto X.
