Well here is it, my first iPhone app! I call it "Hello World" and while It is doesn't do much more than show Apollo 11 and our "World" from lunar orbit, it is my first iPhone app from scratch and it's all mine. The Earth and the Apollo Command Module are animated using the core graphic classes. The result is actually quite hypnotic to watch, with the Earth and Lunar Lander slowly floating by at different rates and vectors.

I must thank Jonathan Lehr at About Objects, Inc. for the great 11 day intensive iPhone development course they hold once every couple of months.

As a technologist, designer and networking geek, I had some C skills coming into the class, but the iPhone Super Bundle, as it is called, really kicked things into high gear. Jonathan covered C, Objective C, the iPhone SDK and all the tricks of using the Xcode IDE and Interface Builder.

so on the flight home from the 11day intensive iPhone development course hosted by About Objects i finally figured out why i could not see my iphone with release 3.0.1 in the Xcode organizer.

the problem:
the iPhone SDK 3.0 does not recognize your development iPhone when
connected to Xcode in the Organizer that has been upgraded to 3.0.1
via your normal iTunes sync process.

Organizer shows you the following error:

"The version of iPhone OS on iPhoneXYZ does not match
any of the versions of iPhone OS supported for development with this
copy of Xcode. Please restore the device to a version of the OS listed
below. If necessary, the latest version of Xcode is available here.
