We've gotten word that AT&T's airwaves in Texas are a bit spotty today due to some sort of "equipment issue" that's causing handsets to be unable to authenticate to the network. Good news is it should be resolved later today, if it hasn't been already -- anyone out there being affected by this? Follow the break for AT&T's official statement.
[Thanks to everyone who sent this in]
Update: AT&T tells us that everything was patched up and good to go as of 7:15 CST.
