Completing a phased roll-out that kicked off back in April, AT&T has finally gotten around to launching its 3G MicroCell in all of its markets, giving the entire customer base some flexibility when "more bars in more places" doesn't happen to include your place. Interestingly, the announcement was made in passing during comments by AT&T director Gordon Mansfield at the Femtocells World Summit in London this week, where he spent much of his time trying to quell a minor furor over the carrier's continued application of data caps when using the MicroCell. He makes some pretty strong arguments: even though all MicroCell voice and data traffic starts off traveling over your own internet connection, it ultimately ends up within AT&T's core infrastructure -- and a legal requirement that the carrier be able to intercept traffic for law enforcement use prevents it from diverting that traffic elsewhere. More importantly, though, if you're within range of a MicroCell, odds are very good that you're also within range of a WiFi connection -- and since all of AT&T's data-heavy handsets offer WiFi, the whole complaint is kinda moot. So just get one if you need one and don't worry about it, okay?
