On Monday's edition of Tech Teardown, Motley Fool tech and telecom bureau chief Evan Niu and host Erin Kennedy look into the biggest stories in tech today. Among the headlines are a possible acquisition of T-Mobile by Sprint, and why sentiment among regulators gives the deal very little chance of going through successfully. Also, Carl Icahn backs down as Apple gets a powerful new supporter for its share repurchase program, which is much more conservative than the one Icahn wanted. Then, a look at BlackBerry's rumored powerful new phone on the way, and whether the move makes sense for the beleaguered company, and a look ahead to NVIDIA's earnings before the company reports on Wednesday.
