Before I begin, I've found a workaround. But it's still pretty darn crazy. My gf bought a new car yesterday. I tried texting my friend what she bought, and what she was looking at. Turns out, you can't type those words. I've had a long, idiotic discussion with the knuckleheads on the Apple discussion boards. Blind devotion to any company is silly. But I digress... Try typing "Lexus", or "Acura" without pressing the little x to correct the iPhone. Can't do it, can you? It corrects the words to "Lexis", and "Acuta". Here's the fun part: The phone won't actually let you type "Lexus" or "Acura", even if you try skimming the keyboard to input the letters. You can type the "Lex" very easily- but the phone is incapable of letting you type the "u". Fun for the whole family! Hold down a letter directly after typing the "x" in "Lexus", (don't press the little x if it comes up). Try forcing the keyboard to recognize the "u". Crazy, huh? It will let you scrub over every letter EXCEPT the "u". Conversely, you can do the same thing with "Acura", and it won't let you type the "r". Yes, you can press the x to correct, and then type. But that's not the point. A slow and deliberate tap on the keyboard on the intended letter, should let you type that letter. But the iPhone doesn't, obviously, in every instance. And yes, you can turn off auto-correction entirely, but that kinda sucks to have to do. If anyone's interested, there IS a workaround. But you would think that you shouldn't have to, wouldn't you?
