Just saw on Engadget that the SDK is available immediately on the Palm Dev Blog, and that they'll be taking app submissions 'in the fall'. Even though I'll wager most people here have already downloaded the SDK, this is great news! All you need is a valid e-mail to get the official stuff.

So what are you waiting for???

(I can't submit links, but if you go to developer.palm dot com, you can access the stuff!)
