Apple’s latest iOS update isn’t even a week old and there is another complaint about it. Reports are in that iPhone 3G owners over in Europe who officially unlocked the phone to migrate to another carrier that Apple has not partnered with are experiencing issues where the Internet Tethering option on the phone has disappeared. This is especially irritating if you often rely on your iPhone to tether when you’re on the move. Apparently thisissue does not affect users who are on a carrier that is contracted with Apple and has not affected iPhone 3GS and iPhone 4 users. There isn’t any official word on this issue just yet, but hopefully it’ll be ironed out sooner rather than later.
