iPodlounge has published excellent in-depth reviews (for both Power Users and Newbies) of Apple’s new fourth-generation (4G) iPod, which began shipping last week. The iPod information and community site has also discovered an apparent manufacturing defect affecting the headphone jacks of certain new iPods. “The defect manifests as audible static and noise interference in the earphones that is most prominent whenever a new iPod’s hard disk is accessed. Similar interference was not detectable through line out (Dock Connector) output.”
