So what? I'm on AT&T and have a 3G connection everywhere but inside concrete bunkers in my city. But that says nothing about coverage. You can say coverage is about HAVING "bars"; better coverage refers to having more area with bars. Coverage of an entire carrier can't be determined by a single case. Additionally, measuring "bars" is useless to the measurement of coverage (1) because the bars on one phone could mean something totally different than the bars on another phone (see iPhone reception miscalculation) and (2) because how many bars you have, or signal strength or reception, is determined in part by how close you are to the signal source. So what if you have perfect reception if you live right next to a cell tower?
