Massucci's Take: AT&T investment boosts coverage and reputation

Two weeks ago, in a post about AT&T's spotty third generation wireless coverage, I posed a simple question: "How about an announcement telling customers how AT&T has been working with Apple to help boost the quality of its iPhone service?"

Now, that seems to be exactly what is happening. AT&T (T) reported on Tuesday that it had spent $65 million upgrading its wireless network in San Francisco since 2008. The phone company said it upgraded about 850 cell sites because of the rising demand put on its network since the iPhone started selling two years ago. That's good news to many iPhone users, whose phone has become synonymous with "dropped calls."
