The iPhone software update 1.1.3 is available immediately for free via iTunes 7.5 or later for all existing iPhone customers in the US, UK, Germany and France. New iPhone products shipping from the factory will include the software update and existing iPhone customers will automatically get the update for free when they sync their iPhone with iTunes.
