Y Yellow Snowman Android Enthusiast Mar 20, 2011 #5 sim card, it does it automatically. thats all you need to know.
willdogs Android Enthusiast Mar 20, 2011 #6 If I am not mistaken, the SIM card if for both 3G and 4G. So they both should be updated via SIM card If you look inside the SIM card packaging you received with your phone, it states DO NOT use *228 plain as day.
