What happens if the iPhone wasn't invented?

Then people would have to find some other way of being pretentious d-bags.

There were other cell phones and had been for many years.

Is it convenient to have a cell phone? Sure.

Is the iPhone a good cell phone? I suppose it's okay.

Is the iPhone so much of an improvement over previous cell phones that it literally transformed society? No. No, it is not. It's just a cell phone, one that's probably overpriced at that. The world would be substantially the same as it is today without iPhones.
