<tangent alert>

How can we actually compare coverage from one carrier to another once roaming is taken into consideration? I use Sprint and very frequently stray from the defined coverage areas on their map. Most of the time my phone doesn't indicate that I'm roaming so I'm a little confused. I haven't had a cell phone plan in years that charged for roaming service so I honestly don't care who's network I'm on as long as my phone works.
