IPHONE4的4.3版本應該會修正此問題吧! http://discussions.apple.com/thread.jspa?messageID=12720693 Just to let you know it seems Apple fixed the issue in iOS 4.3 beta1. Installed it on my iPhone and Volvo V50 can read the tracks again (while it showed the unreadable error when iOS 4.2.1 was installed on my device).
