Apple's revamped and seventh-generation iPod nano has only just begun shipping and showing up in stores, but users will likely find a software update is needed before they can sync the new devices with their Macs. Rather than update iTunes, Apple has opted to issue an update for the software that comes on the iPod to make it compatible with recent releases of iTunes, iLounge reports. The software update, referred to as iPod nano (7th generation) version 1.0.1, does not list any specific issues or changes.
