Steve Jobs dropped the July 30 date for next big rollout during the iPhone 4 press conference but now Apple has gone and made it official:

Beginning this Friday, customers can purchase iPhone 4 in Australia, Austria, Belgium, Canada, Denmark, Finland, Hong Kong, Ireland, Italy, Luxembourg, Netherlands, Norway, New Zealand, Singapore, Spain, Sweden and Switzerland. iPhone 4 will be available for purchase through Apple’s retail and online stores and Apple® Authorized Resellers.

Nice to see, but we'd still prefer pre-orders, reservations, Apple Online Store updates to say something other than "coming soon", official word on when Apple Retail Stores will be open, information from carriers on upgrade eligibility, MicroSIM availability, plans, etc.

You know, everything else required for a launch...!
