This could be cool. Sean Heber of Spiffy Tech is going to release one 3rd party native iPhone app per day in November. Though he might have a spot of help on one or two days, for the most part it appears that he'll have to do most of this herculean effort himself.
If you've hacked your iPhone or iPod Touch, look for the "App-A-Day" source.
It all depends on what the app ideas are. If the app's purpose is to show a pumpkin on the main screen, it could suck. Even if it does suck, it's still a herculean effort.
