In case any of you living in Las Vegas were desperately waiting for T-Mo to pull the 3G switch, your day has finally arrived. As of this morning, T-Mobile has officially went live with 3G in Las Vegas. You’re still stuck with the standard run of the mill crappy handsets if you want to use a 3G one, but T-Mobile promised us they’ve got an HSDPA-capable device coming soon. Yay.
