Leaked iPhone 4G pictures are fast becoming the norm rather than the exception and now more pictures have surfaced before the announcement of the device at WWDC. The latest leak shows pictures of the metal frame which is basically the main housing of the iPhone 4G. Nothing groundbreaking from the latest pictures that we found and it doesn’t seem to reveal anything that we didn’t already know about the device. That being said, you have to wonder what Steve Jobs is thinking about at the moment, as he certainly isn’t going to be pleased with the number of leaks in the build-up to the iPhone 4G’s official announcement.
