Developers accepted into Apple’s paid iPhone Developer Program are reporting that the expiration of the current beta firmware, which happened early this morning, is causing test units to lock up with a pink screen, which says “This device is expired.
Please install a newer version of the OS.” According to TUAW, the affected units can be easily returned to working order by performing a restore with an earlier release of the iPhone or iPod touch software; Apple has yet to comment on the problem, or to release an updated version of the beta firmware.
