What’s better than a developer conference? A secret developer conference of course. Business Insider is reporting that Apple, Inc. will be hosting a “secret iOS developer summit next week.” The event, which is being billed as an invite only, could be an effort by the Cupertino handset maker to polish iOS 4.2 applications that will be ready when Apple makes the next iteration of its mobile OS official. Business Insider cites “an industry source” in the report. It’s all speculative at this point, but we’re sure more information about the double-secret meeting will leak out next week… if it does happen to go down.
