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

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.
