I just downloaded the TypeNine App for .99¢ bringing back memories with T9. I always wondered why Apple didn't offer this as a built in option for English. In Koran there's a full keyboard and one that looks like T9 so why not offer it for English? I like T9 probably one of the few ones out there left.
Do these third party keyboards only get what you type when you use that keyboard or even when you use the built in one?
