Readers report that update 5A240d is now available on the Dev Portal
Reports are streaming into TUAW that official iPhone developers have been hit this morning by the Pink Screen of Expired Release. Their beta licenses for the current 1.2/2.0 firmware distribution have expired as of 12:01am April 8th. Both iPhones and iPod touches now display the pink-backgrounded "This device is expired. Please install a newer version of the OS" activation screen and will do so until Apple issues a firmware refresh.
You can easily downgrade your iPhone or iPod touch from the PSOD. Just restore your iPhone or touch to an earlier firmware release. You will not be able to use your unit for development until Apple updates the developer release but you should be able to make phone calls.
iPhone hacker Nicholas "Drudge" Penree reports that you can bypass 1.2/2.0 activation using the dev team's pwnage tool. He writes that he is aware of 1.2/2.0 iPhones that are still working today.
Thanks everyone who sent this in.
Update: Straight from our blue & green super-sekrit source: "I got bricked as well. Called ADC and they told me there was a new SDK. They said it was stillálabeledáas the old SDK but that if I hovered over the link would show the new one. Not sure how the SDK would fix it vs. a new firmware but I'm downloading it now." I personally can't see any updated SDK material. Perhaps its only available to those accepted into the dev program. Other readers report that they do not see any updates--in the dev program pages or the general iPhone dev center ones.
Update 2: Another blue and green birdie sent us this, which has apparently been posted since the developer program opened: "Important note: Once you install the pre-release iPhone OS on your device, such device may only be used for development and testing purposes until the final (GM) version of the iPhone OS is released. In addition, you will need to install new versions of the software from time to time throughout the beta period. Failure to install the most current version will, after a period of time, put your device in a de-activated state. Updating to the most current version will re-activate your device so that you may continue testing."
Update 3: Apparently the new (possibly 5A240d) firmware seed has only been released to Enterprise developers so far according to yet another blue & green birdie. This birdie tweets that the seed note is quite extensive and includes "unsettling" details. It looks like a lot of device hangs and system restores are in developer futures.
