I bought the Z1 Compact from Handtec in the UK, shipped to the US - when I had issues with mine, I contacted Sony Mobile USA, they had no problem sending me a replacement device from their Texas facility. It took a little longer, because they had to ship the device from overseas to Texas, then to me - but I got it, no hassles. At first, the guy was a little hesitant about whether or not the device was still under warranty, until I reminded him that it had only been on the market for six weeks so it was impossible for it not to be 🙂
