The iPhone 4, the iPhone 3GS, the iPhone 3G and the original iPhone (I think) were all announced at WWDC.

Great, so we're expecting one this time..
Ever released/introduced/demo'd an iPhone at their WWDC before?
Jesus, how petty are you? Do you kno anything about how search results work?
For me, it didn't OK? And it still doesn't.
Perhaps it's because you searched for this "have apple ever release an iphone at wwdc"
"iphone wwdc" clearly gives results that show that Apple always announces the new phone at WWDC, which is also a commonly known fact. You should be more concerned about learning to search; it will affect the results that come up.
