Hi, this might be a very premitive question since I'm not that smart with gadgets: I'm living in the US and am planning to buy an iPad 2 here when it comes out. I need to travel to Korea with it in the summer, and I noticed that they have different voltage... So I'm thinking to buy an iPad charger from the official Korean Apple Store. Here is the link (even if you don't understand Korean, you will get what I'm saying): http://store.apple.com/kr/product/MC359KH/A?fnode=MTc0MjU4NjA&mco=MTczNzY0MzA So, would this be valid/compatible for my US version iPad? or will it harm the device somehow because of different voltage? Thanks in advance!
