For those of you that have tried to access the At&t free wi-fi for iPhone that was reported to be up and running – don’t be surprised when it doesn’t work. The service was up in Texas and California, but is now reported as being down. It’s possible that someone was running a test, and this was a new feature that was not yet supposed to be revealed, and it has been shut down until its official launch.
The iPhone SDK (which is on its 4th revision) is now available for international developers. Apple has also updated text on its official site indicating that the change has happened. You can click here to download.
