CrunchGear posts an internal AT&T memo that was sent out today revealing that the free iPhone Wifi was supposed to be launched today. Unfortunately, the launch has been canceled for unclear reasons:
The iPhone Wi-Fi offer that was scheduled to launch today has been canceled. Nothing has been announced by the company to our customers and will not impact existing customers. Additional communication will be provided if the status the project changes.
AT&T still intends to offer this service as noted by the NYTimes last week, but the timeframe is unknown.
