AT&T dropping "fewest dropped calls" claim

Maybe it stems from Sprint's bellyaching and subsequent legal action, maybe it stems from the fact that the claim was of questionable accuracy to begin with -- but either way, AT&T is no longer spouting off that it has fewer dropped calls than any other national carrier. It's allegedly part of a larger ad shift to the more nebulous (and less legally binding) "more bars in more places" campaign, but really, we suspect there was just a little too much heat coming from various competitors, consumer advocacy groups, and individual subscribers to continue bothering to attempt to back up the statement. So, readers: if it's not AT&T with the fewest dropped calls, who is it? Thoughts?
