This could end up being something that "Might" be released sometime after SDK comes out.
So if any developer develops an APP that allows you to quick access certain areas of iPhone then of course you would have that option.
Again I say "Might" because I really do not know what the developers will do with the SDK when it comes out. But stay tuned to the Discussions and maybe you will read something 🙂
Late February as per Jobs. But that is only when it is released to 3rd party developers. We may have to wait a month or so before we see any apps we can download onto the iPhone as a result.
