As promised, Sony has brought its latest and greatest smartphones to the US. Both the Xperia Z5 and Xperia Z5 Compact are now on sale in unlocked form through Amazon, Best Buy, B&H and other shops at respective prices of $599 and $499. Both pack a fair punch for the price between their Snapdragon 810 processors, 32GB of storage and 23-megapixel rear cameras. The big differences are the displays (5.2 inches on the Z5 versus 4.6 on the Compact) and RAM (3GB versus 2GB). They should work nicely on AT&T, T-Mobile and other American networks that share their frequencies. However, you shouldn't expect exactly the same phone that you'd get elsewhere -- there's a catch.
