Hello, I will be in Tokyo, Japan on the 9th of Feb and I really want to get my hands on an Xperia Z on release date. Does anyone know what will be the best place to get one? I'm not sure if I should go to the Sony Building or to an NTT Docomo store, or somewhere else. I'd really like to be able to reserve one in advance but I don't think that's possible. Also, does the Xperia Z work on global 3G and LTE networks or is it configured to only work in Japan? Thanks!
