Can i make my iPad stop autocapitalizing the word "i"?
It turns out that by writing "i" enough times, the iPad eventually caught on and lets me write the way i want to. I just have to tap the "i" in the keyboard suggestions for a few times, and it seemed to add it to the dictionary.

In fact, while writing this post, i accidentally hit j instead of i and it autocorrected to "i" for me.
