Bloomberg is reporting that "someone familiar with the matter" is claiming Apple's very own antenna expert, Ruben Caballero, warned the company of possible flaws that could have created the issues so many of you are currently experiencing - dropped calls and reception problems.

The report also includes a separate source claiming a particular unnamed carrier also voiced it's concern to Apple over the newly designed antenna system prior of it's release on June 24th. This news all coming in within just one day prior to Apple's last minute iPhone 4 press conference.

Apple has declined to comment and is refusing to grant any interviews with Ruben Caballero.
