We would have liked to see high-resolution stills though and UHD video. The hump at the back is quite a surprise, so much unlike Apple. Aesthetics aside, the wobble is annoying. Easily fixed with the case on, if you don't mind one.
SIM card is already in the phone when it is shipped. You can request unlock without opening the package before you turn on the phone. But you need to plug it to itune to unlock it.
