The original incarnation of Apple's revolutionary smartphone will become obsolete on June 11, according to a document apparently leaked from Apple's headquarters.
Six years after its launch in the UK, the iconic smartphone will no longer be serviced and replacement parts will no longer be produced for it, the document seen by Apple blog 9to5Mac says.
Customers living in California would have their iPhones classified as "vintage" rather than obsolete, enabling them to order parts for the next two years due to a quirk of US customs law.
For the rest of the world, service repairs will have to be conducted through independent stores rather than by Apple's own engineers.
The first iPhone was released in 2007, selling 6.1 million units, and it was discontinued when the iPhone 3G launched in 2008.
Rivals at the time had full physical keyboards, such as those seen on BlackBerries, or keyboards that folded out from underneath the screen.
That all changed with the introduction of iPhone and the App store, and consumers' expectations for smartphones rose quickly to include an easily navigable experience fully equipped for browsing on the go.
Clunky operating systems and a poor user experience were no longer acceptable, and while brands such as Samsung adapted to the new era of smartphones, others, like Nokia, failed to act quickly enough to capitalise on the frenzy for smartphones.
The internal communication added that a number of Mac computers are likely to become obsolete on the same day.
