I got my iPhone 4 new in June 2010, and it's always been set to set the time automatically. A few days ago I noticed it's clock was now running 15 minutes slow. If I set it correctly manually, then turn Set Automatically back on, it jumps back to 15 mins slow again. I've done a soft reset, no luck. Tried turning off/on WiFi, 3G, etc, no luck. My iPad 2, also on Orange UK, and sitting next to my iPhone on the same WiFi networks all day at home & work, is fine, and it's also set to "Set Automatically". What on Earth is going on?
