Apple is seeding a new gold master of iOS to developers, v4.2.1, reports say. Although no notes have been leaked, one source claims that the firmware is aimed at fixing some serious issues with audio and Exchange support in iOS 4.2, which itself received an unusual second gold master distribution last Friday. Apple has yet to push v4.2 out to the public, and the existence of a v4.2.1 preview likely suggests that the former will not reach the general public.
