I bought an iPhone 4 recently, then stuck it in my pocket whilst I went to the gym, so it was sitting in my locker. Unfortunately, a group of my friends that know my locker passcode opened it, changed the lanuage to Chinese (at least I think it's chinese) and buggered off, leaving my iPhone in the locker as if nothing had happened. I'm kinda dead now because I can't do anything on the iPhone because it presents me with a load of gibberish. Can someone tell me how to change the language setting back? The less time it takes the more time I have to chuck their iPhones into a skip.
