As the curtains fell from yesterday’s All Things D conference, one little tidbit of interest was Steve Jobs’ change in attitude about 3rd party apps on the iPhone.

This is a very important trade-off between security and openess. We want both. We’ve got good ideas, and sometime later this year, we can open it up to 3rd party apps.

So there you have it. Not exactly a resounding YES but it’s not a no either. To achieve their need to balance security and openness, they will probably follow the iPod games model which is a controlled distribution of Apple-certified, high-quality apps through a secure channel like the iTunes Music Store.

Now, with that said; what 3rd party OSX application do you think will be best suited for the iPhone?
