Apple is now shipping replacement iPod nanos to customers who had Nanos from a certain batch in the first-generation production run that have been shown to have defective batteries that could, in rare circumstances, overheat or even catch fire. The new units are exactly the same as the replacements, and not brand new iPod nanos (which now hold 8GB or 16GB) as some had hoped. The original Nanos came in 1, 2 or 4GB capacities.
The replacement units are likely refurbished on the inside but include new shells and new batteries. They are otherwise identical to the original units, which debuted in late 2005 and replaced the iPod mini. They were quickly replaced with a second-generation version a year later that introduced an aluminum body, color options and a different battery.
A MacRumors reader reported that although the formal replacement program only began a week ago, he had already received his replacement unit. Previously, Apple had said (in reaction to reports of units overheating or catching fire) that it would replace only those units that had actually overheated. The replacements do not offer the option of replicating the personalized engraving uses may have included on them, and the company says it is the user's responsibility to back up the contents of the old Nano so that it can be transferred to the new one.
Apple says replacement of the iPod nanos subject to the program can take up to six weeks. The replacement Nanos come with a 90-day warranty only. [via MacRumors]
