I changed to the 5 after having the 1 and it fits my hand perfectly as a small phone but I can also appreciate that hand sizes are obviously very subjective
They do! With the US models I’ve been using them in the US, UK and even south Asia and they work great. You’ll need a GSM carrier in the states though.
Xperia phones are better than they’ve ever been. Still have removable storage and headphone jacks btw :)
I’ll also add that I agree that Sony has the worst naming conventions lol
