Just curious, do you guys think you'd actually benefit from having spell-check in iPhone OS 4.0? I know it's going to be there regardless, but I'm just wondering how useful you think it will be. I've heard it's not particularly useful or accurate on the iPad. For me, I'd probably end up turning it off because so many things would not be in the iPhone's dictionary. Is there an option when you tap on a misspelled word to add it to the dictionary?
