For my use, that would be a horror show. Here in Norway we use dialects a lot when texting casually. It's taken me the last 4 iPhones to build up a decent working dictionary, with regard to formal and informal use. Still, even though I use, for instance, "hehe" a lot, my iPhones STILL wants to autocorrect that to "Hege". Annoying as hell, but there's no way I can change that. And no, I don't know anyone named Hege. Not in my adress book, nothing.
