When you unlock your iPhone, what do you see? How do you read your iPhone? Do you see 4, 5 or 6 rows or do you see 4 columns?
Some people see rows. They read from left to right.
Some people see columns. They start at the top and go down.
What do you see?
The early winner appears to be rows...
I did find a single defender of columns!
Prepare to have your mind blown...
Don't get me started on folders...
And thanks to the good folks at Homescreen for the screenshots!
