The Nexus 4 has just gone on sale across the globe and will go live on the U.S. Play Store at 9:00am PST. Initially, it is offered in black only with a funky dot-pattern on the back. It has a glass front and back, and comes for a mind-bogglingly low $299 off contract.
Right now, when you click on the white version over at Carphone Warehouse, there is no image there. We've reached out to confirm whether it really exists or is a technical mistake, and will update you as soon as we get a confirmation.
