Hi! I was wondering if somebody could help me out and give me some advice. I go to college in the US but live in Europe and I want my phone to work everywhere I go. I would love to pre-order but up until now I have no idea which one I should/can get. I have also no idea about which bands are being used in which country or by which provider. I heard that the only phone you can pre-order without an account is the T-Mobile version, is this true? Does anybody have any advice for what I should do? Pre order/Wait in line or wait until the Sim-free version comes out? Will the sim-free be any different than the models sold on launch and how long will it take for the Sim-free to come out? I know these are a lot of questions but I'm clueless.. Thanks!
