A few days ago, pre-orders for the HTC U Ultra started shipping in the US, and now, the device is officially available for purchase in the country. HTC has the phone listed on its official US website, and is selling it for $749.
The model on offer is unlocked, and is compatible with AT&T and T-Mobile networks. This means those on a CDMA carrier like Verizon are currently out of luck. As for available color options, the list includes blue, white, and black.
