Turns out that this concept was first visualized by none other than the co-founder of Apple, Steve Jobs.
Yes, you heard it right!
He wanted it to be a seamless machine.
He had told engineers and designers working on the iPhone that we dont need another hole in it.
For those unaware, CDMA phones dont require a SIM card to link directly to the carriers connection.
[Steve] was such a reductionist.
He didnt want a SIM card slot on the first iPhone.
We dont need another hole in this.
They dont have SIM cards.
Why do we need SIM cards?
Were not going to have SIM cards on our iPhones.
And it had to be a team of us, couldnt be just one of them.
