Since its announcement, we’ve all been speculating about the iPhone 2.0 firmware release date, but Apple has been hiding the date under our noses all along. “iPhone 2.0 software will be available on July 11 as a free software update via iTunes® 7.7 or later for all iPhone customers,” Apple notes in the original iPhone 3G press release (8th paragraph).

Many have told me (3 times 10 times) that this date most likely is a stall date; in other words a “latest possible ship” date for the release. We noted last week that the iPhone 2.0 firmware has already gone gold master (received shipping status); however, we might not see the new firmware until the iPhone 3G is released on July 11th.
