Head on over to the iPhone developer site to get your fresh hot copy of the iPhone 2.1 sdk and beta firmware. It's unclear whether the SDK beta NDA agreement still applies to this new release. In other news: pwnage is now out of date.
Update The developer site keeps going up and down.
Update 2 Er, not so fast. The 2.1 SDK cannot be used for App Store development.
Erica - sorry, but you seem to be a total dweeb. You spend lots of time geeking out about what you can and can't do on the iPhone, and then you release a Flash Light app. What a waste of time!
What does the latest version of the SDK offer for you? A halogen bulb? Or maybe an energy-saver that's better for the environment?
