I'm so driven mad by the iPhone not correcting "noe" to "now" and not correcting "fir" to "for" etc. InSpell is the most awesome app ever, for this reason. It underlines misspellings in red, and lets you add your own corrections to its database. It's a really slick app, too. You can hold down on a misspelling, hit "select", and then "correct," at which point it lets you pick a correct word from its dictionary. I love it. Just wanted to say. The best reason to have a JB'ed iPhone, no question! Just wanted to say.
