I am a heavy texter, about 1,000 a month now. And there are some common words I use that the iPhone automatically "corrects" and makes it into something I don't want. Post some of the common things you spell your way and don't want corrected, but still are. Here are a few of mine:
"lol" turns to "LOL."
"kinda" turns to "kinds" or "Linda."
"noo" turns to "nop."
"lol" turns to "LOL."
"kinda" turns to "kinds" or "Linda."
"noo" turns to "nop."
