SAN FRANCISCO – Apple CEO Steve Jobs says the next iPhone will have a higher-resolution screen, longer battery life and thinner design.

Jobs opened Apple’s annual conference for software developers Monday by revealing the new iPhone 4, which is due to be released June 24. It will cost $199 or $299, depending on the capacity.

It is about three-eighths of an inch thick; the previous iPhone was nearly half an inch. It is getting a camera on the front that could be used for videoconferencing, in addition to a five-megapixel camera and a flash on the back. It can shoot high-definition video, catching up to some other smart phones.

New applications for the device include the popular game Farmville and one from Netflix that lets people watch streaming video where they left off on a PC.
