Quite a lot of features like multi-tasking and folders utilities will arrive with iOS4 update but iPhone 4 will come preloaded with it. The iPhone 4 will require iTunes 9.2 so we can anticipate that iTunes software upgrade in coming weeks. Apple iPhone 4 will be available in white and black colors. Pre-orders begin June 15 and phones will start shipping on June 24 in the US France, Germany, UK and Japan. Apple will roll out iPhone 4 to 18 more countries in July, 24 more in August, and 40 more in September. Let's hope that India would be considered during August or at least September roll out of iPhone 4 device.
