The original implementation of BlindType (the one in all the demos) cannot be used on current iOS devices cause it violates Apple's terms. Apple doesn't want people replacing the default keyboard... so yeah.

They mentioned originally that they would submit to the App Store knowing that it would be rejected, but wanted to force Apple to look at what they were banning due to their conditions.

Once Apple allows it? I have no idea what would happen. Google does release a lot of iPhone apps, but those all tie into Google services. This does not. At all.

It will drive Apple nuts if Android ends up with an obviously superior typing experience than the iPhone. This could be a turning point in their patent war.
