Update: Sony has issued this statement on the matter. In short, nothing has officially changed. Look for the unlocked GSM version to appear in the US this summer.
“A mock-up image was mistakenly posted to the Sony Mobile Google+ page. The image has since been removed and we apologize for any confusion this may have caused. For our U.S. customers eager to find out more information about the availability of Xperia Z2, we are excited to share that the device will be coming to the U.S. unlocked this summer.”
The Sony Xperia Z2 is a flagship worth watching, but here in the US, Sony has only mentioned the possibility of selling the phone in an unlocked version directly through its own website. This is fine, but it limits who can use the phone to those on GSM networks only, namely AT&T and T-Mobile. Yet a blunder made on the official Sony Xperia Google+ page may suggest that more options are on the way. A post there showed an Xperia Z2 with a Verizon logo on it, but it was pulled shortly after going up.
This isn't conclusive proof that Sony's handset is on its way to Verizon, but it does provide reason to hope. We don't have any other information to go on at the moment, so for now we
stare longingly wait.
