"People will simply import iPhones from elsewhere" is not an option - if there's a patent decision, then it would also mean that imports are a patent violation, all iPhones would have to be seized at the customs. Not-for sale items in personal luggage might be exempt, but bringing a new iPhone in a box for someone else would literally be contraband in this situation.
Well yes but smuggling is a very old occupation for a reason. People won't follow a law they think is illegitimate when they feel they can get away with it. So it would work like the war on drugs. Cocaine is very common for a consumable "not an option" for importing.
Hell that same circumstance of personal use is how the underground USSR blue jeans market came about!
