I just tried Photoshop Express, it is a bit crappy, like iPhoto light but right there on the iPhone without having to sync it.
I suppose if you are the sort of person that would take a photo of a car crash and absolutely had to put a basic vignette on it then tweet it then it'll work out for you.
It also lets you straighten photos if like me you have one leg shorter than the other. It's a bit of fun, nothing else.
