I am thinking about buying a Tab S in the US and having it sent to me in Europe because even with shipping it is significantly cheaper than buying here. (Nice little Samsung pricing scam: $399 in US and 399 euros here - a 35% difference!!!!) Is there likely to be a warranty problem OR, more importantly, activation or OS upgrade issues, IMEI or CSC problems? I know it can sometimes be a problem with activations on their phones if they are activated out-of-region.
