When a leaked O2 advertisement showed off the HTC One X+ appeared, it seemed likely that the upgraded model would be appearing soon. Now, just four days later, HTC has officially taken the wraps off. While there aren’t any real surprises, the upgrade adds a bit more shine to HTC’s flagship Android smartphone.The One X+ kicks things off by upping its Tegra 3 processor to 1.7GHz from 1.5GHz, and internal storage has been expanded from 32GB to 64GB. The battery, too, has received a modest upgrade and now packs 2100mAh of power — it’s not a Razr Maxx-style boost, but it’s enough to provide some additional talking and surfing time.HTC has also been busy on the software side of things. The One X+ will ship with Android 4.1 Jelly Bean and HTC Sense 4+. The phone’s camera software has been overhauled, and now features a self portrait mode that offers quick and easy retouching before you upload that new profile pic. There’s also a new sightseeing mode that allows you to bypass the lockscreen and fire up the camera app in an instant by tapping the power button. One other interesting feature is HTC’s new Get Started service, which allows users to complete the initial One X+ setup process from the comfort of a desktop web browser.So far, only approximate launch dates have been revealed — and the U.S. isn’t even on the list yet. The One X+ will go on sale in Europe and northern parts of Asia this month, and then head to the continent’s southern reaches next month. As for the U.S., only the company’s western branch knows when that will happen.via EngadgetUpdate – 10:09am – AT&T has confirmed that it will begin selling the One X+ “in the coming months”.
