Has this happened to anyone else?
I got a notification recommending I let apple automatically upgrade the software on my iPhone, so I clicked yes.  This replaced OS 3.0 with OS 3.1.3.  Unfortunately, now xCode won't let me install or debug programs on the iPhone because it can't handle this OS version, and it prompts me with a list of OS versions it DOES support, which includes 3.0.
So I want to restore my iPhone to OS 3.0 but I can't find a place on the apple website to do this.  Anyone got any ideas?
