AT&T have finally spoken up on the puzzle of their on-again, off-again inclusive WiFi offer.  According to spokesperson Fletcher Cook, the posting of the offer on AT&T’s site was “a human error.”  However, it apparently echoes the carrier’s long-time intention to offer free WiFi to iPhone and other WiFi-equipped devices.

“Our Wi-Fi network is a great way of differentiating the AT&T network and giving customers another reason to choose us over a competitor” Fletcher Cook, AT&T

However Cook would not confirm when the offer would be officially unveiled, and interviewer Saul Hansell of the NYT didn’t push him on why, if the first time was a mistake, it was then added again before being rapidly pulled.  The consensus at the time was that AT&T were having problems limiting access solely to the iPhone.  Many users discovered that they could, by changing their browser’s UserAgent string and entering an authentic iPhone number, get free WiFi without being iPhone owners.
