What I want to know is if Devs can create an app with the SDK and distribute it via installer.app on jailbroken iphones. If so, then we should be seeing awesome apps that leverage the SDK way before June, they will just need to be distributed via installer.app. This may also be a way to circumvent the $99 fee (though only folks with jailbroken phones will be able to download those apps). Folks with access to the SDK, is this possible?
Yes sort of, since there's no app distribution until June anyway.
OTOH the SDK we have isn't a heck of a lot better than what was being used already.. The only new thing is the emulator. The rest consists of a cross compiler limited xcode integration to use it as a text editor. No app design, no helpful ways of adding methods.. it's all harcore right objective C directly just like the existing dev SDK that's around already. I couldn't find any documentation that wasn't a straight copy/paste from the OSX verson either (it even says so at the top).
Basically if you weren't creatng apps with the existing SDK then this isn't going to make it any easier for you.
The SDK that was demoed looked great - but don't expect that to ship until June.
