Apple's wider international launch of the iPhone 4 has been penned in for July 23, according to an Electronista tipster. A source at a major Canadian carrier has the launch marked for that Friday, which would be consistent with the talk of a later July release date for the extra 18 countries involved. The contact warned that the date could move up if other carriers did the same, but Apple has rarely put launches across different dates for providers in a single country.
