iPhone development secrets revealed in a pre-launch leak. Some interesting info on Safari run limits, like 5 seconds max of JavaScript.
Morfik Builds First iPhone Development Tool. I entirely understand the desire to be "first" for anything related to the iPhone, not just to capitalize off of the launch, but to build momentum for a product and be one step ahead of competitors. Developing an app based on speculation and rumor about a platform you can't test with is better than not developing an app at all. If your app is completely broken on launch day, it'll take you less time to fix it than it will someone else to build it from scratch. Nevertheless, I think I'll wait a few weeks before taking claims about development toolkits seriously.
