if they interviewed more people I have a feeling sprint would be dead last. Come on lets push for a interview ALOT more people to get results. 1 tenth of a percent shouldn't speak for the other 99.9
Presuming that they took a true random sampling of their ~46m subscribers, 46,000 respondents (1/10 of 1% of 46m) should give you results with an extremely high confidence level. It's at least one if not close to two orders of magnitude more people then statistically necessary.
