Apple will soon make some of its older products 'obsolete' - spelling disaster for those still using them.
The company defines obsolete products as any that were discontinued more than five years ago.
Under those guidelines, the company's once flagship fourth generation iPhone, named aptly as the iPhone 4, will no longer be in line for software updates - or security patches.
According to reports on Japanese website, Macotakara, and widely echoed around the tech industry press, the cut off date for the iPhone 4 is October 31.
Alongside the iPhone 4 (which cannot be updated beyond iOS 7.1.2), the obsolete list is also believed to include the 13-inch Macbook Air model, which was released in 2010.
Experts are urging anybody who owns either of these products to debate an upgrade.
The news comes ahead of speculation that Apple will be holding an event later in October in which it will reveal updated versions of its Macbook range.
New iPad models are also rumoured for the event, too.
Apple has a long history of dropping technology that it views as outdated.
Recently, the tech giant dispensed with the analogue 3.5mm headphone jack, ditching it from the newly released iPhone 7 in a bid to make way for digital and wireless headphones.
The eagerly anticipated handset was launched at an event streamed live across the globe from San Francisco in September.
