create implication iphone_x -> iphone
create implication iphone_11_pro -> iphone
create implication iphone_11 -> iphone
iphone x is currently used when the distinct front of iPhone X (and later) is visible, or when the distinct back camera housing of iPhone X / iPhone XS is visible, but it doesn't currently implicate iphone.
iphone 11 pro is currently used when the distinct triple cameras on the back of the high-end iPhone 11 Pro (and later) are visible, but it doesn't currently implicate iphone.
iphone 11 is used for the lower-end one which has two cameras. It doesn't currently implicate iphone.
Alternatively, iphone 11 (2 posts) and iphone 11 pro (24 posts) could be collected under the same tag. However, iphone 11 pro is usually used to indicate wealth or high-class; I personally wouldn't ever want to see any iphone 11 images under iphone 11 pro as they give off completely different feelings.
There could be more tags for distinct iphone designs (primarily based on the back of the device), but this is good enough for now.
EDIT: The bulk update request #3156 (forum #170523) has been rejected by @evazion.
