If this add indicates what AT&T considers to be most important to the subscriber, this is sad.
I love the iPhone, but I do not have one because I cannot reasonably justify leaving Verizon to get it. I used to have AT&T some time ago. The reason I left AT&T was because their coverage and service sucked. I have been with Verizon for several years now and their 3G service is much better (using friend's AT&T phone for reference), but most important when using a PHONE is that I get coverage everywhere, and the audio quality, connection quality, and overall satisfaction is superior - Verizon's service is far superior to that AT&T.
I love when these service providers try to take questionable legal action against the competition for presenting their weaknesses to the public, when they know full well that if they weren't true, or the weaknesses were on the other hand, they would be exploiting them in the very same manner.
Truthfully, if Apple really wanted to boost their sales, they would find a way to make the iPhone available to Verizon and other service providers. If Verizon had the iPhone, I would have one. Otherwise, at this point, it looks like my next phone will be an Android based phone.
