Ok. I just got the message from my iPad that it needs to upgrade to iOS 6.1. I haven't got time to study what's the new features, however I try to upgrade as per request of my iPad.. Of course, it is as simple as ONE click on the "Install Now"only as usual.. It seems that this round, the system suggested me to add in Security Question. Oops....too busy, forgot to print screen the questions, but they are like question which need me to recall my memories. Finally, system up..
