Apple has internally prototyped, tested, and considered launching an Apple Pencil for the upcoming foldable iPhone, according to Bloomberg's Mark Gurman. However, he said it is unlikely that the accessory will be released. In his Power On newsletter today, Gurman said the Apple Pencil tested for the foldable iPhone is stubbier than the versions for iPads.

He said the Apple Pencil for the foldable iPhone was designed to magnetically attach and charge on the side of the device. Steve Jobs famously mocked smartphone styluses when he unveiled the original iPhone in 2007. Apple is expected to unveil the foldable iPhone during its September 9 event, and it has been rumored that the device will be named iPhone Ultra.
