Sony has officially added the Sony Xperia ZL to their U.S. web site with a button customers can use to sign up to be notified when the smartphone is available for ordering. No pricing or projected date of availability was provided. Sources indicate the phone will be sim-free and will have LTE antennas available for several bands. The Sony web site lists three colors for the device – red, black and white. The inclusion of the red variant is a nice surprise after that color was shown at an event for South East Asian markets.
