Interesting BBCS. Would be nice to see some sort of scientific study done to control for confounding variables to take into account different geographical locals, different stuctures, time of day, mobile phone type etc. Would need to be independent so that the numbers aren't skewed by the company spin doctors. By "leveling the playing field" like that, the technology of the different carriers would be looked at as the lone variable to compare. Would love to run an SPSS on it to see if their is any correlation/causation relationships and statistical signifigances.
Get me the data BBCS and I will run the chi-square!
