Apple has released an update to iPodis Sotware Updater, an iPod firmware update that fixes the iSleep Bugi, which causes the iPod not to wake from sleep mode when the battery level is low. Apple has issued an alert which characterizes the bug and offers a work-around:
Apple has identified a bug that can cause a small percentage of iPods to temporarily not wake from sleep when the battery reaches a low charge level. Apple has developed an iPod firmware update that fixes this bug. Apple strongly recommends that all iPod customers download and install the iPod firmware update version 1.0.2. This iPod firmware update also provides additional quality enhancements and support for additional languages, including Italian, Dutch and Spanish.
The new Updater software requires either OS 9.2.1 or OS X 10.1, and can be found at Appleis Applecare Knowledge Base site.
