It was rumored that instead of bundling wired EarPods and a charger, Apple would provide a braided USB-C to Lightning cable with each iPhone 12 model sold. Now a tipster who calls himself L0vetodream has shown images of the accessory rumored to be bundled with the new handsets. In addition, he’s also shown images of a black braided cable.

Though L0vetodream didn’t mention this in his initial tweet where he showed an entire gallery of both the white and black braided cables, he later publishes a second tweet, clarifying that the black-colored accessory isn’t meant for the upcoming iPhone 12 family, but is from the iMac Pro. Earlier, alleged renders of the iPhone 12’s inner box leaked online, showing a heavily slimmed down packaging.
