Apple chief executive Steve Jobs displayed the new iPhone 4 which is available for sale from June 24 at $199 with 16 gigabytes of storage, at $299 for a 32 GB model-in an important speech opening the Cupertino, Calif., company’s Worldwide Developers Conference in San Francisco. iPhone 4G looks sleek, and packed with new hardware and multi-tasking software.
