The HTC One X+ smartphone is available at buymobilephones for £27 a month on a deal with O2 spread over two years. The makes for a total cost of ownership of £648, which is more than decent for a newly released, high-end smartphone.

The plan includes 300 minutes, unlimited texts, 500MB data, unlimited UK Wi-Fi courtesy of O2 and BT Openzone, and membership of O2’s Priority Moments loyalty scheme.

The One X+ is, as its name implies, an updated version of the HTC One X, which was unveiled earlier this year. It has a faster Nvidia Tegra 3 SoC clocked at 1.7GHz, 1GB RAM and a whopping 64GB of on-board storage, but no microSD card slot.

Other features include a 4.7in Super LCD2 display with a 1,280 x 720 pixel resolution reinforced by a Corning Gorilla Glass 2 overlay. The One X+ runs Android 4.1 Jelly Bean and also sports an 8-megapixel camera with f/2.0 aperture and a 28mm lens, complete with full HD video recording, HTC Sense plus, Bluetooth 4.0 and a front facing camera.

The HTC One X Plus is also available on T-Mobile (again via buymobilephones) for £15.50 per month on a two year contract with a £220 upfront fee, which yields a much lower total cost of ownership of£592, which may be more attractive for some.
