Last month, Apple announced a worldwide replacement program for the first-generation iPod nano due to continuing issues with overheating related to defective batteries from one of Apple's suppliers.
While some users began receiving their replacement units, which apparently came through as like-new refurbished first-generation units, almost immediately, many other users have been complaining of slow turnaround time for either receiving shipping boxes for returning their defective iPods or receiving the replacement units from Apple. According to reports from users who have corresponded with Apple support staff about the delays, the company has been experiencing shortages of boxes and other items necessary to complete the replacement process.
It now appears, however, that Apple may have run out of refurbished first-generation iPod nano units and may now be shipping out current-generation units as replacements. Several users have reported over the past few days that they have received emails acknowledging shipment of their replacement device's and checking the serial numbers of the replacement devices on Apple's support site has shown them to be sixth-generation models. The sixth-generation iPod nano was originally released in September 2010, and while the line received a price drop and software update a few months ago, Apple still considers the current iPod nano to be a sixth-generation model.
We have not yet received word from any users who have received the sixth-generation iPod nano units as replacements, and thus it remains possible that the serial numbers are simply registering incorrectly in Apple's support database. While we are waiting for confirmation on the possible upgrade, several users have indicated that their shipments are due to be delivered this Wednesday.
