According to some reports, the launch of the Apple’s 3G iPhone will be on June 9 during the keynote presentation at its Worldwide Developers Conference (WWDC) conference.

Rumor has it that no less than Steve Jobs will be introducing the successor to the heralded iPhone on the keynote stage. Apple will also be adopting subsidized pricing schedules for the next-generation iPhone in some countries. This means that certain carriers can offer discounts and subsidies on the iPhone in return for a contract-commitment (or lock-in period) from the customer.
