Swype ported to Apple iPhone, but you still need to spell correctly
The video shows that the software does work on the Apple iPhone keyboard. The one time it failed is a testimonial to the apps ability to make sure that incorrectly spelled words-like, oh, testimonial-do not make it to your screen. Of course, you need a jailbroken iPhone to download this software. You might also notice that the pop-up keyboard would show its face occasionally, but that should go away as the user becomes more used to the Swype technique.
