If they bought/had control of T-Mobile why would that prevent Android phones from being sold on Verizon/AT&T/Sprint let alone on other carriers around the globe?
If that was the case, then the same can be said with an iPhone. How do you know if someone is secretly recording your conversation with the iPhone in their pocket?
Are you sure about that? If I search for "plumber philadelphia", I'm looking at organic and paid sections of the results page. The results in the paid sections tend to be pretty solid. They are local plumbers taking the time out and spending their ad budget online. To me that's a plus, along with a solid website.
