Stocks of the 16GB iPhone are reportedly a little low at the moment and a new report is suggesting that Apple Genius Bars are having to fall back upon stocks of the iPhone 4S in order to meet demand for replacement units. 9to5Mac is reporting that when some customers have taken a faulty iPhone 4 to some Genius Bars in Apple retail stores, Apple have been unable to replace them with identical models. Instead, the stores have been instructed to issue replacement units of the iPhone 4S in the event that there are no matching units of the iPhone 4 in stock.
The report also suggests that not all stores are facing the stock constraints and that Apple may quickly catch up with the low stock levels, so it’s not like there’s going to be a sudden rush of people trying to get their iPhone 4 swapped with an iPhone 4S.
This in’t the first time that Apple has supplemented aging device swap-outs with newer devices. Last year, as part of the recall program for the first generation iPod nano units with faulty batteries, Apple ended up issuing replacement sixth generation iPod nano units to those consumers who had returned a first generation iPod nano that was deemed to be faulty.
