Not much of a surprise here, but Apple has now finally revised its previous “by the end of July” iPhone 4 launch timeframe for some of the remaining international countries to a specific date: July 30th. That includes Canada, Italy a whole host of European countries, plus Australia, New Zealand, and Hong Kong. Absent from that list, however, is South Korea, which had been among the “end of July” group, but has apparently been pushed back to an unspecified date for reasons unknown.
