Sony Store in the US is now selling unlocked units of the Xperia Z3. Sony's latest flagship Smartphone will be available in the US, starting November 10th, for $679.99. Four color variants are on offer - black, white, silver green, and copper - at Sony Store.

If an unlocked handset is not for you, T-Mobile is offering the Sony Xperia Z3 for $0 upfront and a 2-year contract. However, bear in mind that the T-Mobile Xperia Z3 isn't exactly like the international Xperia Z3 variant.
