With the introduction of the new iPad,Apple also released iOS 5.1.
You have to make sure your device has more than 50% battery or has connected to the charger,otherwise,you can’t complete the upgrade process.
The whole process could be done Over-The-Air,so nothing need to be talk about as it’s too simple.Strongly suggest iPhone 4S users to upgrade iOS asap as it could fix the bug affecting battery life.And Siri starts to understand Japanese now,but sorry,no Chinese support yet.So we still need to wait Siri to learn Chinese.
