Hi Everyone This is the first time this has ever happened. I was opening a website link through Twitterific (iPhone app) and the screen has just hung up. If I press any button on the screen or the physical buttons - nothing happens. I've held the buttons for a few minutes to try and do a hard reset (if it exists)... but so far, nothing. I've also tried connecting the iPhone to my Macbook - nothing there again. Any advice?
