Not according to this article. It is actually the iPhone's BUGGY software that is giving ATT a bad name where people are dropping calls with full bars...but in reality they barely even had a bar.
But then again I believe that's wrong because I can change the radio on my phone and go from 2 bars to full bars without moving my phone. The iPhone radio has issues that are giving ATT a bad name.
I love ATT service and I'm in an area dominated by verizon. In fact, it's to the poing now where I joke on my friends and co-workers because they have more areas we go in common and lose signal with Verizon than I do with ATT. They hate it too because they swore verizon is the best in our area.
"...but in reality they barely even had a bar"
Apple is battling the perception issue, AT&T is battling the capacity issue. If the reality is that there really is only one bar, then AT&T apparently can't deliver the connectivity, is that Apple's fault?
