AT&T disables free Wi-Fi for iPhone users


It seemed like a foregone conclusion that AT&T was rolling it out to all of their domestic hotspots nationwide. I have to admit to being a little suspicious of the lack of a press release from either AT&T or Apple, but I just chalked it up to a soft launch while it was being rolled out.
Well, it looks like the party's over.
According to MacRumors AT&T has disabled the free service.
Today, many users are reporting that the free iPhone access has been removed and users are unable to log-in with just their phone number. This appears to be true at locations that were verified to offer the free Wi-Fi access just days before.
Maybe it got too popular too fast? Wasn't ready from prime time? People were spoofing the mobile Safari user-agent to get free access on their MacBooks? Let's just hope that it comes back soon.
What's your theory?
