Bloomberg: Apple engineer was concerned about iPhone 4 antenna early on

As if we needed any more drama in this situation, Bloomberg has someone "familiar with the matter" that claims Apple's own antenna expert, Ruben Caballero, told Apple management that the iPhone 4 antenna design could cause reception problems, dropped calls, and a serious engineering challenge. Caballero is a senior engineer for Apple with a large quantity of antenna patents under his belt, and while we certainly don't know the whole story -- perhaps his claims were somehow quelled by Apple's own testing -- it certainly adds a twist to this story if Steve Jobs and co. had been alerted to this very real problem during the design phase. The Bloomberg article also claims, from a different source, no less, that a carrier partner also raised antenna concerns before the release. Apple and Caballero naturally did not comment on this report. We're not really sure about the real-world implications of all this behind-the-scenes drama, but we suppose we'll see what Apple has to say for itself tomorrow.
