Apple has been saying for some time now that the iPhone SDK would be coming in February, yesterday we found out that that wasn’t exactly true, we won’t even be getting an announcement about the SDK until March 6th. Who knows when we will actually be getting the SDK.

Apple sent out invitations to the press regarding an event talking about “some exciting new enterprise features” as well as the iPhone software roadmap (in other words, the SDK and something that most consumers aren’t going to care about).

The invitation doesn’t come out and say that the SDK will be available that day so it isn’t out of the question to say that the finished SDK won’t be seen until later next month but I don’t think that Apple would leave us consumers with nothing to play with so I would expect Steve to show off a few early applications built by privileged developers that all us iPhone and iPod Touch owners may be able to purchase in iTunes that same day.

I just can’t wait to hear what the restrictions are when it comes to the SDK, whether or not you’re going to be able to have applications running in the background, whether or not developers are going to be able to serve up alerts, etc.

We’ll all have to just wait and see.
