On Tuesday's edition of Tech Teardown, host Erin Kennedy and Motley Fool tech and telecom bureau chief Evan Niu dig into the biggest stories in the world of tech from the market this week. Evan looks at Qualcomm and how its newest processors represent a philosophic departure from its previous approach. He also takes a look at Microsoft's purchase of Nokia's devices business, which was finally approved by the Chinese government. Evan then discusses Cincinnati Bell and its decision to sell its wireless carrier business to the top dog in the space, Verizon.

And finally, a look at two stories happening within Apple today. Evan discusses the company's efforts to develop baseband processors for its own devices, and how this could hurt longtime baseband supplier Qualcomm, and he also takes a look at some direct evidence that the iPhone 6, expected to launch later this year, will in fact be a larger phone.
