Hi, I have had my iPhone 5 for a couple of days and am no longer getting 3G from my desk at work, which I've previously had consistently with my iPhone 4 and iPhone 4s. I have no idea on why this will be... Also, when visiting web pages, I'm also getting a '403 denied' error when visiting most webpages e.g. Apple.com - but all my apps are connecting to the internet fine e.g. Twitter. Is anyone else having similar problems?
