It appears that some iPhone 4S owners are having trouble activating their new handset. And so far, it appears that the trouble is limited to AT&T's network.
Early this morning, Cult of Mac reported that people across the "blogosphere" were complaining that they weren't able to activate the iPhone 4S on AT&T's network due to too much strain on the carrier's servers.
Those owners said that the activation process got hung up when the device displayed a screen saying, "It may take up to 3 minutes to activate your iPhone." Perhaps most notably, Cult of Mac said that it has yet to come across folks who have experienced issues activating their new smartphone on Verizon's or Sprint's networks.
