MacNN reports that according to its sources, some developers are getting early iPhone SDKs. Apparently, while still in the early stages the SDK resembles Google’s Opensocial in that it mediates between the programmer and the iPhone.
Exact details on what the kit allows are unknown at this time, but it is clear that writing an app for the iPhone won’t be the same as writing an application for OSX.
Those of you hoping to build homebrew emulators with the iPhone SDK can probably forget it at this point. Apple is going to keep a lock down on this as best they can, and my guess is none of the current “native” iPhone apps for hacked devices will be making their way over to the official iPhone release.
Hopefully, we’ll have some cool iPhone applications by Macworld…but that is purely speculation on my part.
