Okay so.. When I go to send a text message, it keeps saying "Message failed. Would you like to retry?" Eventually, after so many times, it says, "SMS problem. Code 64." Then the other number is 2. I don't know what it's called... I have service and WiFi on. And I even have 3G network.. It also says it can't find my time zone. I don't know what's happening... Help???
