The first replacement units sent to customers through Apple’s iPod nano 1G Replacement program have started to arrive. Mac Rumors reports that although the model was discontinued five years ago, the replacement units are indeed first-generation iPod nano units, with the same capacity as the units that were replaced. Notably, reports indicate that the replacement units are in like-new condition, suggesting that Apple is at the very least offering refurbished units as replacements, complete with the new battery and outer shells that come standard with Apple refurbished models. Apple recently launched the replacement program as a way to deal with potential safety risks caused by faulty batteries.
