I can only give you an opinion from my POV. The iPhone 5 was released in 2012. After that one, the phones kept getting bigger and bigger. Maybe Jake just prefers carrying around a smaller phone. Plus, it was a damn good phone. I didn't ditch mine until 2019 (when the bastards stop supporting it)
Jake has multiple burner phones so it would make sense he wouldn't have the newest phones.
I also had an iphone 5 until 2019 lol it was amazing phone especially for its time but it was basically trash by 2020
Is anyone else curious abt which year the story is taking place? Im confused here
There are a two things that spesifically stood out to me:
We saw both jake and shin use iphone 5's so it would make sense if it's the early 2010s. Idk about shin but i imagine Jake would have a high end phone. I cant really say that for certain tho since theres one thing that ruins my theory:
Jake's car. Its a McLaren 570GT which was -i believe- introduced in 2016. So the year were looking for cannot be before 2016 but the iPhone 5 is already pretty old in 2016 so im getting even more confused.
I may just be looking too into this i dont know
